Recording, mixing: Doctor Robert

Studio Two, EMI Studios, Abbey Road
Producer: George Martin
Engineer: Geoff Emerick

The Beatles had recorded the backing track for ‘Doctor Robert’ on 17 April 1966. Two days later they completed the song, in a session lasting from 2.30pm to midnight.

All the instruments had been recorded in the earlier session, so the only overdubs needed were of vocals. Artificial double tracking was applied to these during the mono mixes, three of which was made in the evening.

The original session recording contained the “Well well well” section three times. The last of these was edited out of the final mix, reducing the running time by 41 seconds.

A different, slightly longer, mix was used for the US album Yesterday… And Today, and was made on 12 May 1966. Stereo mixes were created on 20 May.
