Studio Two, EMI Studios, London
The Beatle's work at EMI Studios on this date can be separated into two distinct sections: 3:00-4:00 pm rehearsing and 5:30-9:30 pm recording.
The afternoon rehearsal, which was not taped, replaced a pre-booked 2:30-5:30 recording session and was swiftly arranged by Brian Epstein to familarize session drummer Jimmy Nicol with the Beatles and their material. Just a few hours earlier, Nicol had been pottering around his home in Barnes, west London, when a telephone call came through from George Martin, on behalf of Epstein, inviting him to become a temporary Beatle. Ringo had been taken ill during a photo session that monring and since he was now in the hospital it was clear that he wouldn't be going out on tour with the Beatles the following morning. With some urgency, Nicol was recruited as his temporary replacement.
So, Nicol went to EMI where, instead of recording, the three remaining Beatles ran him through a half-dozen songs in their present stage routine - "I Want To Hold Your Hand", "She Loves You", "I saw her standing there", "This Boy", later, John, Paul, George and Jimmy were on stage in Copenhagen, giving their first concert.
When Nicol left the studio, John, Paul and George remained behind to do some recording (documentary evidence that this session took place, and it's details, only came to light in 1991). In Ringo's absence, each of the three took the opportunity to tape simple demo versions of recent compositions. The resulting tapes were taken away either by the composers or by their music publisher Dick James, for they were deposited in the Abbey Road tape library, not then nor any time since.
George began the 5:30 to 9:30 pm session, recording a demo of a song entitled, "You'll Know What To Do"? Paul followed, taping a demo of a revised arrangement of "It's For You", in order that he could give Cilla Black for her exclusive release. The third demo was made by John, of new composition "No Reply". This would be issued later in the year on the album Beatles For Sale. John made this demo because he donated first use of his song to fellow NEMS artist Tommy Quickly, for release by him as a single. Towards 9:30 pm, John, Paul and George returned to EMI four-track recording, taping overdubs onto "Any Time At All" and "Things We Said Today".
