As with the recording, the mixing took place at Trident Studios in London's Soho. The session began at 2pm and ended at 1.30am.
In that time just three stereo mixes were made, the last of which was judged to be the best. On 6 August 1968 they mixes Hey Jude in mono, before taking the tapes back to Abbey Road for further work.
