The opening track is "Real Love", the second of the two recordings that reunited the Beatles for the first time since the band's break-up.

The three surviving Beatles (McCartney, George Harrison and Ringo Starr) added guitars, bass, drums, percussion and backing vocals, but unlike with the previous song, did not re-work the lyrics or music.

Disc one contains three unreleased compositions, one being an instrumental entitled "12-Bar Original", recorded for Rubber Soul but subsequently unused.

The take of "Strawberry Fields Forever" that made up the first minute of the released record appears in its entirety on track three.

McCartney had hoped to include "Carnival of Light", an unreleased experimental piece that the Beatles recorded during the sessions for Sgt.

Pepper in 1967; however, the idea was vetoed by Harrison, Starr and Ono on the grounds that the track was never intended for a Beatles release.

[2] Among the songs that were in the running for inclusion on the compilation but ultimately passed over were the following: the 1965 Shea Stadium performance of "She's a Woman"; a live version of "Nowhere Man", recorded in Tokyo in 1966; "Paperback Writer", featuring only vocals; and out-takes of "Think for Yourself" and "Love You To".
