After the Beatles' EMI contract expired in 1976, the company began assessing the band's unreleased material for a future release. The first batch of songs to leak came from an in-house compilation cassette that contained "Leave My Kitten Alone", "One After 909" (from 1963), "If You've Got Trouble", "Christmas Time (Is Here Again)", "That Means a Lot", "Come and Get It", "Dig a Pony" (unedited version), and two medleys from the "Get Back" / "Let It Be" sessions: "Rip It Up / Shake, Rattle and Roll" and "Not Fade Away / Bo Diddley".
