However, a few had the 1945 opening version of that song — some cartoons had the standard length of the Blue Ribbon title sequence, with the audio from the original credits playing over the part where the cartoon's title is shown ( such as Farm Frolics, Old Glory, Wacky Wildlife, and Tick Tock Tuckered ), while others had a shortened version of said sequence ( edited to fit the length of the music ; cartoons with this style opening included Lost and Foundling and Trap Happy Porky ).
If the reissued cartoon was a Merrie Melodies short originally released between late 1941 and early 1945, then the opening music would have been the same from the original release ( unless the reissue had the 1945 music ), but in other cases, the opening music is different from the original.
