Here’s an early 1990s clip -- 1 of 2 -- of youngish African-Americans dancing spiritedly to hip hop music in a dance studio in Fremont, California. 

They are dressed casually and appear to be friends or close colleagues. One guy wears a lime green shirt that reads, “YO...POWER 92 JAMS!” Another guy wears a dark green Oakland A’s jacket. Another person wears a UCLA Bruins sweatshirt. Another wears a shirt that says, “BEST DAD EVER!” And one wears a t-shirt of Syracuse’s Orangemen. The sole woman in the group wears gold hoop earrings and shirt and shorts that bear the “Florida Memorial College” logo.

They stand before a mirror, dancing by themselves but also in unison. They goof around with each other as well as the camera person. No doubt, they are having a good time.
