The Beatles album was supplemented by the four tracks already released on their first two singles. Martin originally considered recording the Beatles' debut LP live at The Cavern Club, but after deciding that the building's acoustics were inadequate, he elected to simulate a "live" album with minimal production in "a single marathon session at Abbey Road".

The Beatles You (She's So Heavy)" on 20 August 1969 was the last occasion on which all four Beatles were together in the same studio. Lennon announced his departure to the rest of the group on 20 September, but agreed to withhold a public announcement to avoid undermining sales of the forthcoming album. Released six days after Lennon's declaration, "Abbey Road" sold 4 million copies within three months and topped the UK charts for a total of seventeen weeks. Its second track, the ballad "Something", was issued as a single – the only Harrison composition ever to appear as a Beatles A-side.
