A reduction mix was firstly created to allow for more overdubs. This mix, numbered take nine, combined both of Paul McCartney's vocal tracks into one, and piano and drums onto another.
Two more tracks of backing vocals were then recorded, and rhythm guitar added to the choruses. The song was then left until 16 September 1967.
This was The Beatles' final recording session prior to the death of their manager Brian Epstein on 27 August 1967. Epstein was actually present during this session, although his involvement was minimal.
He came in to hear the playbacks looking extremely down and in a bad mood. He just stood at the back of the room listening, not saying much.
