Beforehand, from 2-4pm, a press call took place at Abbey Road, with numerous reporters and photographers being invited in through the normally closed doors.
The session took place from 5-8pm. The musicians were: Sidney Sax, Patrick Halling, Eric Bowie and Jack Holmes (violin); Rex Morris and Don Honeywill (tenor saxophone); Evan Watkins and Harry Spain (trombone); Jack Emblow (accordion); and Stanley Woods and David Mason (trumpet). Stanley Woods also played flügelhorn on the recording.
The BBC camera crew, directed by Derek Burrell-Davis, was also present. Camera angles were decided upon, as was the positioning of The Beatles and the orchestra during the broadcast.
In the evening four more rehearsal takes were recorded. These were numbered 44-47, and took place during a simultaneous reduction mix.
On this day the decision was made to release All You Need Is Love as a single after the broadcast.
