I sent an email that may or may not reach one of the series' sound editor, credited there as TC Spriggs.

Is there a message board for the show where someone may have nabbed a copy and could check the show credits for you if no one here has any luck?

Is it stuck in your head, in which case I'd advise you hum or whistle or sing that tune into the nearest recording device (even your voicemail), so you don't lose it.

We've all been there. Heck, some would say this whole site here owes its existence to it! :~)
