Beatles
Phish covered the Beatles' The White Album in its entirety on 10-31-94.
Phish's "Alumni Blues" is on their own White Album.
"Cavern", one of Phish's earliest tunes, is also the name of one of the Beatles' first venue.
Each band had an early fifth member, about whom there is some history and some mystery: the Beatles' Pete Best 1962 and Phish's Steve Holdsworth in 1984.
"Music hath powers to soothe the savage breast."
-- Ken Kesey (in his review of the Merry Pranksters at phish, 8/14/97)
