Since no one has bothered to answer this for you, and my curiosity is now piqued, I will go find out and let you know. If it was instrumental only, then chances are good it is something written by the show's theme composer(s) and possibly on the soundtrack CD. If not (since I don't remember the song offhand) I'll let you know when I figure it out.
