In preparation for the US album Yesterday… And Today, mixes of three Revolver songs were made during this session for Capitol Records.
Of the songs recorded so far, it was decided that ‘Doctor Robert’, ‘I’m Only Sleeping’, and ‘And Your Bird Can Sing’ would make the cut. During this session, which began at 1.45pm and finished at 3.30pm, mono mixes of the songs were made.
The mixes of ‘Doctor Robert’ and ‘I’m Only Sleeping’ were each done in a single attempt. ‘And Your Bird Can Sing’ was more complicated, however, and involved different mixes being made from takes 10 and 6. These were edited together at the end of the session.
The mix of ‘Doctor Robert’ was also edited slightly, as, incidentally, were the mono and stereo mixes made for Revolver.
There were 3 unique stereo mixes to I’m Only Sleeping that differed from the Revolver album (they appeared on the US-only Yeaterday & Today LP). The backwards guitar sounds fade up and down at different spots in the mix.
Dr. Robert also had a different mix than what appears on Revolver.
