Trident Studios, St Anne’s Court, London
Producer: George Martin
Engineer: Barry Sheffield
This session, which took place at London’s Trident Studios between 6pm and 1am, saw more overdubs added to Savoy Truffle and Martha My Dear, plus the creation of a number of mono and stereo mixes.
George Harrison added his lead vocals onto Savoy Truffle, with Paul McCartney adding additional harmonies. McCartney then overdubbed electric guitar and bass onto Martha My Dear.
Three songs were then mixed in mono: Honey Pie, Martha My Dear and Dear Prudence. Each was done in a single attempt, although Dear Prudence was given another mix at Abbey Road on 13 October 1968. Honey Pie and Martha My Dear were then given their first stereo mixes.
