I wanted to show a video that blows my mind but it cannot be displayed here. The Beginning of the End is the video title of the song Funky Nassau with the dancers of Soul Train busting their moves in pairs and they are very entertaining to watch. The fashion is outrageous and the shoes quite incredible. One young woman dancer kicks high as her head toward the camera, had the strap broken on her heavy white clog shoe and it flung, it would kill you. Among them, an older couple dances smoothly, others acrobatically, we see the incipient moves of break dancing and robot moves and all sorts of moves being busted in sequence.
