Funny Rock'n'Roller Parody

Did you recently go to the movies? I usually don't. But by accident this week I got to watch Walk Hard – The Dewey Cox Story.
This 2007 movie is a complete biography of a Rock'n'Roll star – yet a fictional one. Dewey Cox as a kid learns to play the Blues, plays in a Highschool band, steps in for a famous singer and becomes a star on its own. Sex, drugs and Rock'n'Roll now guide him through his life – to prison, rehab, and comeback. The funny thing is that this biography combines everything you ever read about the rock stars' life.
Dewey meets a karate Elvis. He visits the Maharishi with the Beatles. And of course he works for Jewish brothers running a record company. There's an episode on a Sonny&Cher-like TV show. His band breaks up during a many-months-long work on a new song with full orchestra (including a goat) with Dewey looking like Brian Wilson. And there's a Dylan-style folk protest concert.
You have to know the common rock stars and their biographies to get most of the jokes, but if you do, this is really funny. And you may learn that Punk was invented in the late 1950s. Highly recommended!
