|I don't know the tv series, and never heard the music either. I do know that for tv series around that age, the music was usually composed for the tv series. So its possible this is a custom made song.
Googling gives me this video too:
http://www.youtube.com/watch?v=agPPSksV4uM (season 3 theme)
The music there is: Powerman 5000 - Nobody's Real
Maybe they also did the theme for season 1?
You can ask me hundreds "why don't you" questions, answer will be, because it works that way too. - xTr1m
