When I was growing up in Chicago in a primarily African-American neighborhood in the mid 70s (This was probably 1976-1978) we used to do a song where a small group of us would stand in a circle and take turns doing little dance solos with different body parts, for example if Jane, Susan and Mary were in the circle we would all sing:

"Jane's got the rhythm, rhythm in her arms" and while Jane would move her arms around we'd all sing "Umm, check it out, umm-umm check it out", then "Susan's got the rhythm, rhythm in her hips" and Susan would swivel her hips around while we all sang "Umm, check it out, umm-umm check it out" and on and on with each kid doing a different body part (head, legs, butt, waist, etc.) we all agreed in advance who would do each body part before we all started singing.

It's 35 years later and I still get that song stuck in my head sometimes and nobody here in California seems to have ever heard it...
