Trident Studios, St Anne's Court, London
Producer: George Martin
Engineer: Barry Sheffield
The session took place at Trident Studios in London's Soho, which had been chosen for its eight-track recording facilities. Overdubs added to take one included lead and backing vocals, bass guitar, tambourine, handclaps, and a 36-piece orchestra.
The orchestra featured 10 violins, three violas, three cellos, two flutes, contrabassoon, bassoon, two clarinets, contrabass clarinet, four trumpets, four trombones, two horns, two string basses and percussion.
The session musicians were also asked, for a double fee, to clap their hands and contribute backing vocals; one musician reportedly refused, saying: "I'm not going to clap my hands and sing Paul McCartney's bloody song!"
