::::::: While I myself don't think the "black" people back then danced in a "breakdance-style" or did any form of bboying at all, it very much has similar movement points if you look at the Youtube videos. A wild dance-style element for instance. And moves that are not too easy for the untrained one, even a bit acrobatic, so here I agree that both dance styles have an element in common. I am not sure if this is enough to warrant a historical connection, but it could be that the earlier dance style influenced the later one. 178.190.203.159
