Room 65/Studio Two, EMI Studios, London
Mono and stereo mixes of "The Word" were produced in Room 65, probably in the Beatles' absence, between 4:00 and 5:30 pm. The Beatles began recording at 6:00 pm, one hour ahead of time, in this final Rubber Soul session, and they also worked four hours beyond its 3:00 am scheduled end, clocking up 13 uninterrupted hours in studio two. They knew that the deadline had come, that their new album had to be finished this night. They also knew that they needed three more songs. Paul came up with one, John another, and for the third they pulled off the shelf "Wait", the discarded Help! track, added various bits and pieces and pronounced it fit for inclusion on the new LP. Balance was everything in 1965: a 14-song album meant seven songs per side and everything hunky-dory. (Still, despite the pressure, no one considered including on the album either or both songs on the new single, "We Can Work It Out/Day Tripper".
Paul's song, "You Won't See Me", was recorded from start to finish in two takes, as was John's song, "Girl", then the Beatles added tone-pedal guitar, tambourine, maraca and more vocals onto take four of the five-month-old "Wait", overdubbed vocals onto the previous night's "I'm Looking Through You" rhythm track and, suddenly, to the accompaniment of the St. John's Wood dawn chorus, they knew that the new album was complete.
