@flash56: For another great music mockumentary, check out The Rutles: All You Need Is Cash. It's a 1978 spoof on The Beatles, written and directed by Eric Idle of Monty Python. Idle plays McCartney, Neil Innes of The Bonzo Dog Doo Dah Band plays Lennon (Innes wrote all the songs for the movie, great parodies of specific Beatles songs), and one-time Beach Boy Ricky Fataar plays Harrison. Also appearing are Harrison himself, Mick Jagger, Paul Simon, Ron Wood, and a bunch of the SNL cast (Lorne Michaels produced the movie).
