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.
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.
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.
The day ended with the aforementioned edit of two mixes of Maxwell's Silver Hammer, followed by editing of Sun King/Mean Mr Mustard onto 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.
