Following a previous day of rehearsals, The Beatles recorded six takes of Everybody's Got Something To Hide Except Me And My Monkey.
The sixth take was the best, and lasted 3'07". Two reduction mixes of this, numbered takes seven and eight, were then made, with the tape machine running at 43 cycles per second rather than 50, so the song was faster, shorter, and in a higher key upon playback.
The Beatles then added further overdubs, so that by the end of the session at 3.45am the song featured drums, lead and rhythm guitar parts, and a percussion track featuring handbell and chocalho in alternating verses.
Further overdubs followed on 1 and 23 July 1968, including vocals and bass guitar.
