The session lasted from 5.30-9pm, and began with George Harrison recording a demo of You Know What To Do, which remained unreleased until Anthology 1 in 1995; documentation for the session was discovered in 1991, but the tapes only came to light in 1993.
Harrison first recorded a test version of the song lasting just 30 seconds. It was followed by just one full take, lasting 1'56", which was later issued on Anthology 1.
The second song was a version of You're My World, which had been a hit for Cilla Black earlier in 1964. It was not a Lennon-McCartney composition, but had been produced by George Martin and recorded at EMI Studios, Abbey Road.
McCartney led Lennon and Harrison through a brief, off-the-cuff rendition of You're My World lasting for a little over 30 seconds. It has been reported that on this day they also recorded a demo of It's For You, a song which was later given to Cilla Black, but this did not happen.
The third recording was a demo of John Lennon's No Reply, which eventually surfaced on Beatles For Sale. Curiously, a drummer is on the tape, although Nicol had departed by this time. It is likely that McCartney filled the drum stool on this occasion, and that Harrison played bass guitar.
There has also been speculation that, had Starr not been taken ill, one of these songs would have been included on A Hard Day's Night, which was, unusually, released with 13 tracks.
