NPR just put up a delightful short fluff piece with a newly released early take of The Beatles setting down verses for “Lucy In the Sky With Diamonds.”
The most fascinating thing about it is Lennon’s performance. He sings in straight eighths on words like “tangerine” and “marmalade” instead of syncopating them. Also, the vocal timbre is less stylized or instrument-like at the beginning, whereas in the final version it is basically filtered to get more overtones and fit the weird quasi-harpsichord electronic organ that Paul’s playing—think Billy Corgan. Finally, John is accompanied by a slightly distracting mechanistic bass drum on downbeats instead of the softer (and harmonically functional) bass guitar, but they probably already knew they would make that change, yeah? Paul can’t be everywhere at once.
Glimpses of the creative process for tunes like this often show how making something more aesthetically consistent (like fitting John’s voice to the overall style of the verse) means to make it more extreme, to “stylize” it even more.
