McCartney recorded the basic track on piano in a single take, as well as live vocals. John Lennon was present in the studio control room, and the balance engineer was Phil McDonald.
A copy of the mix was also made for McCartney to give to The Iveys. He produced their recording at EMI Studios on 2 August 1969.
The demo of Come And Get It was included on Anthology 3 in 1996, although this was a fake stereo mix - with the treble slashed in one channel and the bass in another - prepared by Geoff Emerick in the 1980s rather than the 1969 mix.
The rest of the day, from 3.30-10.30pm, was spent working on Sun King/Mean Mr Mustard, two John Lennon songs recorded as one for the Abbey Road medley. During this and the following day's session, the two songs were known under the working title Here Comes The Sun-King.
Thirty-five takes were recorded, with The Beatles all playing their conventional instruments: Lennon and Harrison on electric guitar, McCartney on bass guitar, and Starr on drums. A distortion pedal was used by McCartney during Mean Mr Mustard.
During the session Lennon led the group through a cover of Ain't She Sweet, followed by versions of Gene Vincent's Who Slapped John? and Be-Bop-A-Lula. As with Come And Get It, Ain't She Sweet was included on Anthology 3.
