I saw this interview and then remembered this thread. It doesn't answer the question, but it does give an idea of how they approached the recordings. A couple examples, they had Paul cut a word off because it was going to go into John's recorded part. The recorded the orchestra on one channel. Pretty good perspective of how they approached the recording sessions. (Grimm, I know this is old news to you )
I have to say that Geoff Emerick seems to be a pretty down to earth guy.
