Spector and Apple artist Billy Preston each played piano on a track. During the sessions, Lennon, Voormann and Starr jammed on a variety of songs in between recording the new tracks: "When a Boy Meets a Girl", "That's All Right Mama", "Glad All Over", "Honey Don't", "Don't Be Cruel", "Hound Dog" and "Matchbox". They also taped the basic track for Starr's "Early 1970" in which the drummer describes his relationship with each of his former bandmates; in the verse dedicated to Lennon, Starr sings, "They screamed and they cried, now they're free".
