Get Crazy is one of my top five favorite movies that has yet to be released on DVD. It's directed by Allan Arkush, who helmed Rock 'n' Roll High School and used to be an usher at the Fillmore East in its glory days of the late '60s and early '70s. This film's his tribute to it.
It's about a New Year's Eve concert at the Saturn Theater, owned by a very Bill Grahamy Allen Garfield and assisted by a young Daniel Stern. There's more sex, drugs, and rock 'n' roll than you can shake a microphone at. And what a cast - Ed Begley Jr.! The Doors' drummer! Paul and Mary Bland! Fabian and Bobby Sherman! Lou Reed (with a sense of humor!!)! Clint Howard as an usher! And above them all, Malcolm McDowell IS Reggie Wanker!
Sparks performs the title track, with the great lyric "Get crazy / Tell your boyfriend that you're pregnant / Watch him smile." I'm telling you, this is one you've got to track down.
