I've always known that song as "Guitar Rag", but then again that name has been used for other similar instrumentals. Maybe someone here (Rickipedia, where are you?) can help you out.
Don't know the original broadcast date, but the taping itself took place on Oct. 22, 1998 at
Sony Music Studios in NYC. Something tells me you already knew that, though. Ha!

Ooby Dooby!
