Re: Emerick and the "Underwater Vocals" on "Yellow Submarine"

I mean, we know John was taking acid by then.  Lennon had yet, by the
time of "Yellow Submarine" to have showed up in the studio blatantly
fried and unable to function -- although I know that's coming soon.
There is a passage in Emerick's book where Lennon shows up in such an
acid-ravaged state.  George Martin thought John seemed in need of a
breath of fresh air, and took him up to the roof -- only to leave him up
there.  When the other guys realized Lennon had gone missing and asked
George Martin about it, they raced up to the roof to retrieve Lennon --
who fortunately hadn't persuaded himself that he was Jesus.  Yet.
