In 1995, after the Beatles released Lennon's " Free as a Bird " and " Real Love " with demos provided by Ono, McCartney and his family collaborated with her and Sean Lennon to create the song " Hiroshima Sky is Always Blue ", which commemorates the 50th anniversary of the atomic bombing of that Japanese city.

These included selected early demos and takes for Lennon's " Strawberry Fields Forever ", previously available only to bootleg collectors.

Many of Lennon's demos that appeared on bootlegs were first heard on the radio series The Lost Lennon Tapes.

The idea of re-doing some of Lennon's old songs apparently was inspired by former Beatles road manager Neil Aspinall and Harrison, who first requested some old demos from Lennon's widow, Yoko Ono.

Particularly famous ones include George Harrison's Concert For Bangladesh, The Concert for New York City following the September 11 attacks, and John Lennon's final concert appearance ( during an Elton John concert on Thanksgiving Night, 1974 ) before his murder in 1980.

According to the bootlegged album of the songs recorded at Kinfauns, George Harrison's Esher home, these include Lennon's " Look at Me " and " Child of Nature ", eventually reworked as " Jealous Guy "; McCartney's " Junk " and " Teddy Boy "; and Harrison's " Not Guilty " and " Circles.

It featured such classics as John Lennon's " Imagine ", Cat Stevens's " Where Do the Children Play?

" He then brought up Lennon's comments about " Why Don't We Do It in the Road?

Others included " Mean Mr. Mustard " and " Polythene Pam " ( both of which would be used for the medley on Abbey Road ); " Child of Nature " ( recorded with drastically different lyrics as " Jealous Guy " for Lennon's Imagine ); " Etcetera " ( a McCartney composition ); " The Long and Winding Road " ( completed in 1969 for the Let It Be LP ); " Something " ( which ended up on Abbey Road ); and " Sour Milk Sea " ( which Harrison gave to friend and Apple artist Jackie Lomax for his first LP, Is This What You Want ).

During their collaboration, Elton John appeared on John Lennon's song " Whatever Gets You Thru the Night ".

Mangum played 13 songs, about half of them from Aeroplane, and covered Phil Spector's " I Love How You Love Me " and John Lennon's " Mother ", with Chris Knox joining him on the latter.

Walls and Bridges was an American Billboard number 1 album and featured Lennon's only number 1 single as a solo artist during his lifetime, " Whatever Gets You thru the Night ".

The album also includes some of Lennon's most uplifting songs, namely its two singles " Whatever Gets You Thru The Night " ( which features Elton John on piano and harmony vocals ) and "# 9 Dream " ( the instrumentation literally evokes a dream ).

Their cover of John Lennon's " Whatever Gets You thru the Night " is the second single from the " Instant Karma: The Amnesty International Campaign to Save Darfur.

" Whatever Gets You thru the Night " is noteworthy as John Lennon's only US number one solo single while he was alive.

His gallery also hosted " You Are Here ", Lennon's own foray into avant garde art during 1968.

In 2011, a track Guy had written with Julian Lennon entitled " Never Let You Go " was released on Lennon's comeback album " Everything Changes ".

Before take 15, Harrison delivered a mock press statement in a joking reference to Lennon's absence and the British pop group Dave Dee, Dozy, Beaky, Mick & Tich: " You all will have read that Dave Dee is no longer with us.

This song belatedly acknowledges the influences of John Lennon in particular, which was very strong on " If I Had You " and " Everybody's Got To Learn Sometime " which capture the ethereal sounds of Lennon's early 1970s output.

The excerpt on the Let It Be album fades in on Lennon's second " Like a rolling stone " and concludes with Lennon speaking in a falsetto: " That was ' Can You Dig It?

Pinder also appeared on John Lennon's " Imagine " album in 1971, providing additional percussion on " I Don't Wanna Be A Soldier ( I Don't Want To Die )".

In 1994, McCartney agreed with Lennon's description of the circumstances surrounding the composition of " I Want to Hold Your Hand " saying:

The album was released less than six months after Lennon's death and deals with it directly in songs such as " Goodbye Sadness " and " I Don't Know Why ".

The 1997 Rykodisc reissue added bonus tracks of the single " Walking on Thin Ice " and an a ' cappella demo of " I Don't Know Why ", recorded the day after Lennon's death.

The piece, titled " My Mummy Was Beautiful ", was dedicated to Lennon's mother, Julia, who had died when Lennon was a teenager.

The poem was an intro to a performance of the song " Imagine ", Lennon's anthem to world peace.

The day ended with a cover of " Twist and Shout ", which had to be recorded last because John Lennon had a particularly bad cold and Martin feared the throat-shredding vocal would ruin Lennon's voice for the day.

A number of songs were recorded during these sessions but were not issued on The Beatles, including Harrison's " Not Guilty " ( which he re-recorded for his eponymous 1979 album, George Harrison ), Lennon's " What's the New Mary Jane ", and McCartney's " Jubilee " ( later retitled " Junk " and released on his first solo LP ).

Other songs recorded for, but ultimately left off The Beatles received significant exposure via bootlegs, notably Harrison's " Circles " ( which he eventually re-recorded as a solo track and released on his 1982 album, Gone Troppo ) and " Not Guilty ", and Lennon's manic " What's the New Mary Jane ".

Included on this album is " God Part III ", which draws on John Lennon's " God " and the U2 riposte (" God II "); " Come Away ", written about his 1973 meeting on the streets of Shepherd's Bush with prostitute Holly Valentine, who later became a Christian ; and the autobiographical " Under The Eye ", " which tells how Larry has, despite the last decade, always been watched and cared for ".

At the beginning of the Let It Be version of the song, Lennon can be heard jokingly saying " Sweet Loretta Fart ( often misheard as " fat ", due to Lennon's pronunciation ), she thought she was a cleaner, but she was a frying pan.

Another song featured on the album was " 20 Years in the Dakota ", which discussed Yoko Ono's struggles as John Lennon's wife, a position which Love herself has been frequently compared to, due to the perception that Ono drew Lennon away from The Beatles and that Love drew Cobain away from Nirvana.

Lennon's inspiration for the song came when his son, Julian, showed him a nursery school drawing he called " Lucy-in the sky with diamonds ", depicting his classmate, Lucy O ' Donnell.

The song has the distinction of being the first Beatles recording to be referenced by the group themselves: the second verse of Lennon's " I Am the Walrus ", released on Magical Mystery Tour at the end of 1967, contains the lyric " see how they fly, like Lucy in the sky, see how they run ...".

The songs included originals and four covers: John Lennon's " Happy Xmas ( War Is Over )", Mike Batt's " A Winter's Tale ", " When A Child is Born " and Bing Crosby's " White Christmas ".

The album included 11 new recordings, featuring covers of Joni Mitchell's " River ", Gordon Lightfoot's " Song for a Winter's Night ", and John Lennon's " Happy Xmas ( War Is Over )", which she recorded with her outreach children and youth choir, and seasonal favourites: " Christmas Time Is Here ", " O Little Town of Bethlehem ", " Have Yourself a Merry Little Christmas ", " Silent Night ", " The First Noel ", and " Greensleeves ( What Child Is This?

The ballad evolved from " Hey Jules ", a song widely accepted as being written to comfort John Lennon's son, Julian, during his parents ' divorce.

:* The song " Don't Look Back in Anger " from ( What's the Story ) Morning Glory ( 1995 ) features a piano line near-identical to that of John Lennon's solo hit " Imagine ", as well as a bridge section instrumentally reminiscent of " Octopus's Garden " and featuring a Lennon quote in the lyric (' so I start a revolution from my bed ').

Chapman recalls having listened to Lennon's John Lennon / Plastic Ono Band albums in the weeks before the murder and has stated: " I would listen to this music and I would get angry at him, for saying that he didn't believe in God ... and that he didn't believe in the Beatles.

An article in the Daily Mail about a plan to fill potholes in the town caught John Lennon's eye as he was writing the song, giving birth to the lyric " I read the news today, oh boy / 4, 000 holes in Blackburn, Lancashire / And though the holes were rather small / They had to count them all / Now they know how many holes it takes to fill the Albert Hall.

Also, during this time the band contributed a cover of John Lennon's " I Don't Wanna Be a Soldier " to the 1995 John Lennon tribute album, Working Class Hero.

In July 1971, Curtis recorded saxophone solos on " It's So Hard " and " I Don't Wanna Be a Soldier Mama I Don't Wanna Die " from John Lennon's Imagine.

Pang recalled the younger Lennon's response, telling his father " If I'd known, I would have played better ".

Having lost the wager, Lennon appeared at John's Madison Square Garden show on 28 November, performing Lennon's current number 1 hit together as well as The Beatles ' " I Saw Her Standing There " and " Lucy in the Sky with Diamonds ", ( which was Elton John's new single with Lennon on backing vocals ).

" A Day in the Life " is a notable and well-known example of a later Beatles song that includes substantial contributions by both Lennon and McCartney, where a separate song fragment by McCartney (" Woke up, fell out of bed, dragged a comb across my head ...") was used to flesh out the middle of Lennon's composition (" I read the news today, oh boy ...").

I got into the car and I put the key into the ignition and Lennon's voice came straight out of the radio and it was Lennon song Starting Over.

When McCartney arrived at Lennon's Weybridge home for a writing session, he had the tune in his head, but " The lyrics were disastrous, and I knew it.

On their 1988 album Rattle and Hum, U2 attacked Goldman's allegations about Lennon in the song " God Part 2 ", " sequel " of sorts to Lennon's song " God ", with the lyrics " Don't believe in Goldman / his type is like a curse / Instant karma's gonna get him if I don't get him first.

The intro to " I Feel Fine " starts with a single, percussive ( yet pure-sounding ) feedback note produced by plucking the A string on Lennon's guitar.
