This is Edd Kalehoff, composer of much of the "Price Is Right" music, performing the Schafer beer jingle on the Moog synthesizer (and then pouring himself a cold one).

This is the earliest game show I have a distinct memory of watching: "The Cross-Wits," which in 1979 was airing weeknights at 7:30 on Channel 13 in Tampa.

But I remember it in black-and-white -- we didn't have a color TV yet.
