The Muso: Jarvis Cocker

Cocker plays a character called Petey, who looks suspiciously like his real-life counterpart.

While his song for the film is still in place, his narration was removed because the studio was worried US audiences wouldn't be able to penetrate his Sheffield accent.
 
Appropriate Lyric: "Mis-shapes, mistakes, misfits, We'd like to go to town but we can't risk it, oh, Cos they just want to keep us out. You could end up with a smack in the mouth, Just for standing out, Oh really."
