I just want to state that, for the record, I don't condone filming people who are minding their own business. I never saw the video, and I probably wouldn't even understand the point of the video or why someone filmed this dude other than to be an ass.

That said, we live in a very "connected" world. If you don't want yourself to end up on the internet, then don't do anything out of the ordinary in public (and that includes Phish shows, which are very much public). It's similar to the web. If you don't want people to see it, don't put it there to begin with.

@mpike: There is no assumption of privacy for anyone, including regular folks, like you and me, when one is in public. That includes a Phish show. Sure, Trey, being a celebrity, has no assumption of privacy when he's performing, but if you're out in public, people have a right to take a picture of you. They don't have a right to use your likeness to make money (at least not without your permission), but they do have a right to take a picture or video.
