As far as I understand they hired a guy to do the theme music for the show. His name is Neil Sutherland and you can contact him on his site. Although I doubt you’ll have much luck, seeing as many have tried and the answer still isn’t out there on the internet.

I think this is the song you’re looking for on youtube, but it’s pieced together from various segments. I find this version some guy made on his own much better. Now having two youtube videos with sound, what’s to stop you from using a site like http://www.video2mp3.net/, copy in the youtube url and download the mp3 file?

Worked for me, I hope that answered your question.

Yeah, I had seen the version that that guy had had made on his own. Not bad.
