The Beatles completed work on two songs, and began another, during two sessions on this day.
The first session took place from 3.30-8pm in Abbey Road's Studio Two. Two mono mixes of Revolution, numbered 20 and 21, were created.
Ob-La-Di, Ob-La-Da was the second song to be tackled. Paul McCartney had decided to re-record his lead vocals. Background contributions from the rest of the group included various jokey noises such as forced laughter, and "arm", "leg" and "foot" after Molly or Desmond let the children lend a hand.
Ten mono mixes were then made, which were numbered 12-21. This saw the completion of Ob-La-Di, Ob-La-Da, doubtless to the relief of the group.
The second session started at 9pm and finished at 3am on the morning of 16 July. The Beatles began work on Cry Baby Cry, although these were unnumbered rehearsal takes rather than proper attempts. Four reels of tape were filled, but unfortunately most of the recordings were erased in subsequent sessions.
