Kid patt vs. Mr. styles

I love this video. Two school aged boys having a good old fashion clean dance off, surrounded by a group of kids. Just havin' some good clean fun. One kid dances until one of his sneakers falls off. Remember me of being a kid and hanging out with the neighborhood group. They don't even have music and improvise with clamping and making music with their mouths. While watching them I could not help but think: I wonder if this is how the slaves used to do it?
