I've always noticed something in the way John sang some lines ...
Lucy In The Sky With Diamonds ... spicealley the way he sang these words:
"Follow her down to a bridge by a
foun-tain"
[...]
"Everyone smiles as you drift past the
flo-wers"
[...]
"Picture yourself on a train in a
sta-tion"
[...]
"Suddenly someone is there at the
turn-style"
...
I Am The Walrus ... spicealley these lines:
"I am he as you are he as you are me and we are all together
See how they run like pigs from a gun, see how they fly"
[...]
"Mister City Policeman sitting
Pretty little policemen in a row.
See how they fly like Lucy in the Sky, see how they run."
[...]
"Crabalocker fishwife, pornographic priestess,
Boy, you been a naughty girl you let your knickers down."
[...]
"Expert textpert choking smokers,
Don't you thing the joker laughs at you?
See how they smile like pigs in a sty,
See how they snied."
[...]
"Elementary penguin singing Hari Krishna.
Man, you should have seen them kicking Edgar Allan Poe."
...
Come Together ... almost all the lines (except "Come together right now over me") ... his rythm singing them :
...
I can imagine a
rapman "singing" them quite easilly
...
