Here is some more footage and it appears to be from the same performance. Anyone have any idea what year this is from?

Hey Spellbound:
The footage is from Sylvester's appearance on The Midnight Special, December 1, 1978. Sylvester also sang You Make Me Feel and Grateful.

I cannot climb down from the energy I get from watching these two clips. The fun I see is just too infectious

Thank you both, for posting them, and telling us where there from.
