Continuity mistake: In the Fish and Chip van, the guy with the pony tail says, "I'm going to fart." The next few shots have his head alternating in different positions even though there was no time for him to move.
Audio problem: Near the end of the movie: In the last club scene, an acoustic piano can be heard. Notice that is different than a regular piano. However, when we see the piano it's a Fender Rhodes piano, and not an acoustic. OK, it could be another piano, but the club only has the one piano.
Outspan Foster: What's that? A Mister Chippy van?
Mickah Wallace, Drums: We can't travel in that shit heap.
Joey: Buddy Holly's last words.
Joey: We can't travel in that shit heap.
Outspan Foster: Did Buddy Holly say that?
Joey: Before he flew to meet his destiny on that storm-tossed night.
Outspan Foster: Will crashin' in a chipper van make us famous, huh?
