For Vol 2, the anthology contains 63 tracks total, including 37 previously unreleased performances and 23 previously unreleased recordings of in-studio banter and conversation between the band's members and their BBC radio hosts.

Ten of On Air's songs were never even recorded by the Beatles for EMI in the '60s, and two songs make their debuts with the new release: The Beatles' direct-to-air performance of Chuck Berry's "I'm Talking About You" and a cover of the old standard, "Beautiful Dreamer."

On Air also includes different versions of six rarities heard on the 1994 BBC collection: Little Richard's "Lucille," Chuck Berry's "Memphis, Tennessee," Chan Romero's "The Hippy Hippy Shake," Ray Charles' "I Got A Woman," and two songs they learned from records by Carl Perkins, "Glad All Over" and "Sure To Fall."
