Though we already knew "The Devil Went Down to Georgia" was going to be in Guitar Hero 3 we didn't realize it was going to be the final track (the end boss, if you will). A helpful press release just informed us of the distinction while pointing us to this MP3 file of the now fiddle-free version. Gone is the violin and in its stead is, of course, a guitar – a fast guitar – played by one Mr. Steve Ouimette who, when asked for comment said, "I told you once, you son of a bitch, I'm the best that's ever been."
Peep the entire track list to date after the break (with helpful YouTube links!).
