Saturday Night Fever

This article was the inspiration for the movie.

Then the music changed to Baby Face, and a boy in a red-patterned shirt began to dance alone. He came out of nowhere, down from the tiers of seats at the very back of the hall, the bleachers, which were completely shrouded in darkness. Skinny, shrimpfish, he stood out in the very center of the floor, caught by the swirling lights, and did one half of the Rope Hustle. Only half, of course, because the Rope Hustle cannot really be performed without a partner.

So he twirled in irregular circles, his arms twining and unfurling about his neck, vaguely as if he were trying to strangle himself. And the Faces at the bar, without even seeming to look, began to snigger.
