Thanks to David: Apparently, this is Madonna's first-ever on-air performance—it's a spirited rendition (mimed) of "Everybody" from 1982. The dancing is effortlessly fluid and mesmerizing even then—Madonna, Bags and Erica Bell were quite a team pre-Christopher (wah-wah) Ciccone.

Check out the hapless blond boy attempting to dance behind them, and the happenin' little number in the yellow turtleneck workin' a closeted-gay boogie.
