Hutzal mentioned a video of Ira Bernstein (which is also mentioned in a thread on clog dancing). Well, I haven't seen the video, but the man can dance! he dances several different styles of step/clog/tap dancing and he can talk about the background and characteristics of all of them, even just after having danced one with great energy. He also sings and he plays the fiddle and the fiddlesticks.
