A 12-hour session took place on this day for the mixing, editing and crossfading of various Abbey Road songs. It took place in the control room of Abbey Road’s Studio Two from 2.30pm-2.30am.

The day’s first task was to create stereo mixes of ‘Sun King’/‘Mean Mr Mustard’. Five were made, and were numbered mixes 20-24.

‘Maxwell’s Silver Hammer’’s final verse was then mixed in stereo. This was numbered remix stereo 37, and later on during this session it was edited with the previous best mix, remix number 34.

Thirteen mixes of ‘Polythene Pam’/‘She Came In Through The Bathroom Window’ were the next to be made. These were remixes 20-32.

The crossfade from ‘You Never Give Me Your Money’ into ‘Sun King’/‘Mean Mr Mustard’ was attempted 11 times on this day, which used tape loops assembled by Paul McCartney on 5 August 1969. It was, however, improved on 21 August in a single attempt, which became stereo crossfade mix 12.

During the session John Lennon gave an interview to BBC Radio 1’s Kenny Everett for the show Everett Is Here. The interview was broadcast in two parts on 20 and 27 September 1969.

The day ended with the aforementioned edit of two mixes of ‘Maxwell’s Silver Hammer’, followed by editing of ‘Sun King’/‘Mean Mr Mustard’ into ‘Polythene Pam’/‘She Came In Through The Bathroom Window’. By 2.30am around half of the Abbey Road medley was complete, with final work on the other songs taking place in the coming days.
