If you haven't seen it yet, you must find VH-1's documentary Soul Train: The Hippest Trip in America. It's worth seeking out.
Cast members from 2007's This Christmas dance the Soul Train line.
My favorite scenes in the 2007 theatrical release movie This Christmas are the ones with the whole family together dancing the Soul Train line. The above clip is from the end of the movie just before the closing credits. Here, the entire cast comes together to dance--some of the actors are having so much fun, they are breaking character! This scene reminds me of the power of Soul Train. It was greater than than just a TV show, becoming a part of all of our lives.
