kingarthur The Derailers do a country version of this that's a lot more fun. Still, five stars for cross-pollination.
godot Hayseed Dixie do this sort of thing exclusively.
Jet Bin Fever I wanted to like it a lot, but the recording is so terrible it really bothers my ears. The bass thump cancels out the mic. Also the guys voice is pretty poor... so 4 for the idea at least!
