** Tammi Terrell, American soul singer ( d. 1970 )

Also buried there on March 20, 1970, is 1960s Motown Soul / R & B singer Tammi Terrell.

Following the death of Tammi Terrell in 1970, Gaye went into seclusion, emerging the following year with " What's Going On " and its subsequent album, which helped to make him one of the first artists in Motown to break away from the reins of Motown's production company to be his own artist.

On March 16, 1970, Tammi Terrell succumbed from brain cancer.

Tammi Terrell ( born Thomasina Winifred Montgomery ; April 29, 1945 — March 16, 1970 ) was an American recording artist, best known as a star singer for Motown Records during the 1960s, most notably for a series of duets with singer Marvin Gaye.

Ross ' version was produced by Nickolas Ashford & Valerie Simpson, and was built around the same thematic basis that made Ross ' 1970 remake of Marvin Gaye & Tammi Terrell's " Ain't No Mountain High Enough " a success.

The composition was first successful as a 1967 hit single recorded by Marvin Gaye and Tammi Terrell, becoming a hit again in 1970 when recorded by former Supremes frontwoman Diana Ross.

* Jean Terrell, R & B and jazz singer, replaced Diana Ross in The Supremes in 1970.

The Supremes ' final appearance on the show, shortly before it ended, served as the platform to introduce America to Ross's replacement, Jean Terrell, in March 1970.

When Diana Ross left the group in 1970 for a solo career, singer Jean Terrell was brought in as her replacement, and the group was re-christened " The Supremes ".

The " New Supremes " – Wilson, Terrell, and Birdsong – continued their hit-making process from 1970 through 1972 with hits like " Up the Ladder to the Roof ", " Stoned Love ", " River Deep – Mountain High " ( with the Four Tops ), " Nathan Jones ", and " Floy Joy ".

In 1970, Jean Terrell replaced Diana Ross as lead singer of The Supremes.

After Ross's farewell show with the group at the Frontier Hotel in Las Vegas on January 14, 1970, Terrell joined the group on stage to be presented to the press and public.

Terrell would have eight unsuccessful operations before succumbing to the illness on March 16, 1970 at the age of 24.

By early 1970, Terrell had been forced to be confined to a wheelchair, suffered from blindness, hair loss and weighed a scant 93 lbs.

Following her eighth and final operation on January 25, 1970, Terrell relapsed into a coma where she would remain for the next month and a half of her life.

The lead vocals were recorded separately by the two singers and combined during the mixing process, reportedly to cut studio time, and give time for Terrell, who was using a wheelchair, to recover from surgery to repair the malignant brain tumor that would ultimately cause her death in 1970.

In 1970, the same year that Diana released " Reach Out and Touch " as her first solo single, ironically the song was also covered by the group that she had just left at the start of that year, The Supremes ( now fronted by Jean Terrell, along with other members Mary Wilson and Cindy Birdsong ).
