Dude, LATE Beatles are trite and clunky. The LATE Beatles that did songs like Rocky Raccoon and shit, that stuff is lame. The early Beatles were tight, and smart and were sorta the blueprint for a lot of the other british invasion bands. If you don't like the Beatles pre-1965 I don't see how you could like ANY British invasion music from the same time.... everyone gets a pass on I Wanna Hold Your Hand and all the really really really huge hits, but songs like All I've Got To Do, Not a Second Time, I'm a Loser, those songs are classic and they are NOT clunky, they're sharp, and smart, and quick.
Also, the Beatles invented the trick of recording your drums, bass and guitars faster than you wanted, then slowing down the tape to the tempo you wanted, makes em sound bigger. Chris Bell used that trick on the song I Am the Cosmos.
