I'm reminded of an episode of the Simpsons when Homer states: "Let your freak flag fly!" The phish community that I've known would be embracing and sharing in this type of improvisational behavior. The man is obviously getting deep into the music. How can we judge him. So what if he is acting outside the "normal range" of behavior. The beauty is in the raw creativity.

I love seeing all kinds of weird, intuitive, ritualistic, hoe-down dancing and the phish crowd usually brings it. Don't judge it people, just let the music in and see what happens.
