Baby It's You - The title track is the same performance as the one on Live at the BBC, minus the amusing Sha la la la la! intro that appears on that collection.
I'll Follow the Sun - This McCartney song from Beatles for Sale was performed in November 1964 to promote the upcoming release of that album.
Devil in Her Heart - This seems to be the only instance where a BBC session inspired the group to go into the studio and record a song for an album in the works, which they did only two days after this performance for With the Beatles. The casual air of these sessions is apparent here as George, John and Paul clearly muff the lyrics on a few occasions, yet the recording was broadcast nonetheless.
Boys - Ringo's vocal spotlight from Please Please Me was recorded seven times for the BBC.
In the selection of tracks for the group's first new EP in almost thirty years, the inclusion of Baby It's You and Boys strikes me as being no coincidence, since they were the only songs from their first album Please Please Me which had not appeared on EPs back in 1963 and '64.
