 "Bad Boy" was not released in the UK until "A Collection of Beatles Oldies", and was that album's only cover song.A few songs that were recorded and intended for the album and film were not used.Lennon and McCartney wrote "If You've Got Trouble" for Ringo Starr to sing, but the Beatles were not satisfied with the song and it was abandoned, and Starr sang "Act Naturally" instead.
