I can't really add anything to this, except that the song is quite lengthy and staring at the image made me "trip." In a very bad way.
And if you enjoyed that clip (I really don't know if that verb could ever cover it), please check out this poster's other offerings. He has done tribute songs for Marilyn, Jackie O., Ben Franklin, Diderot, Blaze Starr, JFK, Elvis, Voltaire, and Che Guevara. King Frederick of Prussia and Lyndon Johnson "singing" are indeed great, but MLK is a personal fave of mine.
