Nine hours, 2:30-11:30 pm, spent recording and completing Paul's new ballad "Michelle". From 2:30-7:00 the Beatles perfected the rhythm track in one take. At 7:00 this was reduced into take two to vacate a track on the four-track tape, and from then until 11:30 they filled this with vocal and guitar overdubs.
