During some US radio interviews, Lennon was asked if there were any unissued Beatles recordings, he replied that all he could recall was "some lousy 12 bar".
Starr told journalist Peter Palmiere that "we all wrote the track and I have an acetate of one of the versions".
The quote was later used by Palmiere in a Ringo Starr cover interview/story in DISCoveries magazine in 1993 and by Jim Berkenstadt and Belmo in their book Black Market Beatles.
