Everybody remembers John Travolta's spectacular dance in 'Saturday Night Fever ' (1977, Paramount). But who remembers the Puerto Rican couple that cleaned his clock in the dance competition? I do! Here is the clip of that couple doing some sort of Latin Hustle (which starts out with a Mambo step).

BEWARE: There is profanity and racial epithets used generously in this clip!

Especially BEWARE: This is the 70's.
