Following a six-day hiatus, The Beatles resumed working on Strawberry Fields Forever in a session which began at 2.30pm and ended at midnight.
George Martin had prepared a score and booked session musicians to play the brass and string parts. The trumpeters were Tony Fisher, Greg Bowen, Derek Watkins and Stanley Roderick, and the cellists were John Hall, Derek Simpson and Norman Jones.
Martin conducted the musicians as they recorded their parts onto tracks three and four of the four-track tape. A reduction mix, numbered take 26, was then made to free up space for more overdubs. After this the rhythm parts filled track one and all other overdubs were on track two.
Five mono mixes, numbered 5-9, were made towards the end of the session, and acetate discs were cut for each of The Beatles to take home.
