Interestingly, they hadn't created an edit of the closing theme yet where they chopped off the intro. If you listen closely to the closing credits, a little bit of the intro before the main tune starts is present.
It was also good to hear it without applause. The Griffin shows at the time always did that if they were running a bit late - instead of the host saying "goodbye", they'd go right into the fee plugs (from commercial) without applause and then the applause would start as soon as they were over. Wheel of Fortune did that frequently back then as well.
