If anyone has played this game on the original X-Box Live Arcade, I'm sure you're familiar with the music that plays on the main menu, that is what I'm looking for. Does anyone have this or know where to get it?

Alright, a few updates. The guy who did the intro music I'm looking for is John Mullins. I also downloaded the demo for Guardian but the sound file is in a .FLX format which I cannot open.
