This was the first day the orchestral instruments were recorded for All You Need Is Love. The musicians were also present for the next two sessions, culminating in the worldwide satellite broadcast Our World on 25 June 1967.
Four violins, two cellos, two saxophones, two trombones, two trumpets and an accordion were recorded playing George Martin's score. It took 10 takes, numbered 34-43, but this may have been because a reduction mix was being simultaneously created.
The session took place from 8-11pm. The takes were never released, and were largely to check that the recording would work on the day of Our World. Similar rehearsals took place on 24 June.
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.
