Okay, I've been trying to find out who's doing the theme song, and I can't find it. My friend couldn't remember but described it as some kind of Simple Plan-like band. I'm probably too much a fan of the Waylon Jennings version to accept anyone else singing it, though. Of course, they're salving that wound with Willie Nelson as Uncle Jessie.
So my question: Who is doing the theme song for the movie?
