I Want You (She's So Heavy)
Three takes from 22 February were edited into a master (second generation), which was overdubbed, mixed down on 18 April (third generation), and overdubbed on 18 April, 20 April, 8 August and 11 August. Different overdubs were made to the second generation tape on 8 August. The mix is the third generation for 4:37 and then the second generation tape, which has white noise produced by the Moog synthesizer played by Lennon and additional drums added on 8 August. The final overdub session for "I Want You (She's So Heavy)", which included the final mixing and editing, was the last time all four Beatles worked in the studio together.
