I know/have known hundreds of musicians and hardly any are what might be called 'good' dancers. Most won't even try unless it's their daughters wedding or something. The one or two that were decent were both drummers. Don't know what that means. In any case, I guess they (musicians) were learning to play while everyone else was learning to dance. I wonder which group ended up with the hottest chicks (ugghh, that sounded a little bit sexist). Also, I think most musicians (not 'entertainers') are a little bit introverted (shy, self-conscious) which is why they are better able to express themselves behind the protective barrier of an musical instrument. Just a guess, though.
