Speaking of Beatle quality material, has anyone ever listened to the Rutles ? They were in a 'spoof of the Beatle story' movie called "All you need is cash" {it has cameos from George Harrison, Paul Simon, Ronnie Wood and Mick Jagger} in the late 70s. Anyway, the music from the movie was written by a guy called Neil Innes who was in the Bonzo dog doo dah band, contemporaries of the Beats {they're in Magical mystery tour}. They are very deliberate attempts to sound Beatlesque but in my opinion, they are stunningly brilliant and utterly hilarious if you dig the Beatles. They deliberately draw on many Beatle songs and they cover every stage of the Beats' career. For me, they stand on their own as great songs and would've done, even if I'd never heard the Beatles' stuff.
