When I read this by Geoff Emerick I cant help feeling that his personality was changed during 1967, in a way like Syd Barret (Pink Floyd) and Peter Green (Fleetwood Mac) but to a lesser degree
Geoff Emerick on the making of Lucy in the Sky: John’s “Lucy in the Sky With Diamonds” (which also ended up being banned by the BBC because the title words spelled “LSD”) was up next, and it soon became one of my favorite tracks on the album. It was actually done very quickly- including rehearsal, it took only three nights to complete. By this point the four Beatles were starting to get a little fed up with being stuck in the studio. After all, they’d been there for nearly five months and it wasn’t the dead of winter, the weather was starting to brighten, so they were probably starting to get itchy. I know I was
By now it was evident that John’s personality was changing. Instead of being opinionated about everything, he was becoming complacent; in fact, he seemed quite content to have someone else do his thinking for him, even when he was working on one of his own songs. By the spring of 1967, he was becoming increasingly disengaged, and that would more or less continue until the end of the Beatles career. No doubt Paul was aware of the situation, and he was seizing the opportunity to step in and expand his role within the band.
That manifested itself down in the studio as they worked on this song, with John’s lead vocal getting less aggressive and more dreamy with each successive take. That might have been a reflection of what he was smoking behind the screens, but Paul was clearly steering him in that direction, too. We had decided to route George Harrison’s guitar through the Leslie speaker during the choruses, and because that reminded John of the Dalia Lennon vocal effect from “Tomorrow Never Knows”, Mal was duly dispatched to see if he could find a rope so John could try out his theory, that you could get the same effect by swinging around a microphone suspended by a rope. From the wink that Mal gave me when he returned some hours later, empty handed, I suspect that he had spent the evening in the pub instead. He knew how absurd, and potentially dangerous, the request was, and he probably guessed that John would have forgotten all about it by the time he got back, which, of course, is exactly what happened.”
