"If I Needed Someone" was the first priorty of this afternoon session, from 2:30 to 5:45, George's lead vocal, John and Paul's backing vocal and Ringo's tambourine being overdubbed onto the previous night's take one rhythm track.
The remainder of the afternoon was spent taping another marvellous new John Lennon song, the autobiographical "In My Life". The "best" was take three, completed but for a gap left in the middle-eight section which was plugged with an imaginative overdub on October 22nd.
