I completely agree about Alice's Restaurant: so casual ("We're just waiting for it to come around on the guitar again", like it was an independent being. Audience in the palm of his hand.)

A few splendid Beatle moments:
The bass line in "Hey Bulldog" -- not my favourite Beatle song, but it sure moves. (like "Ballad of John and Yoko" -- McCartney made that song.)
Speaking of George Harrison, that hint of slide things to come in "For You Blue".
The opening of "Day Tripper".
The opening of "I Feel Fine".
(weel, we could go on all day about this one.)
yours, Peter T.
