There's nothing in this world quite like prime Michael Jackson, and his performance of disco-pop masterpiece "Rock With You" on longtime friend Diana Ross' 1981 TV special is about as peak MJ as it gets. The singing is predictably heavenly — though not so immaculate that it comes off as lip synching — and Michael's dancing, in a white suit with a sequin shirt, is every bit as smooth as the song feels. An identically dressed Diana even joins him for an encore of this one, approaching on creepy in her obvious envy. "Diana, you've got plenty of hits of your own!" Jackson reassures. "Yeah, but I want your hits!" Understandable.
