DNJ, I agree...stage presence is key, but standing up and stage presence are 2 completely different things. I think we can all agree that just because a person stands up, doesn't give him or her good stage presence. It's how you communicate, your energy, your competency as a keyboardist, how clearly you pronounce words, how well you communicate your material to the crowd etc....I guess standing or sitting doesn't define an artists work in my mind. Can it add to a show? depends on the performer, but I'm willing to bet that if a performer can wow a crowd standing up, if he sits down during the the second half of the show, it will not effect his show or the audiences acceptance of the performer one bit...again, if it works for you, and you appear to be really successful, I'm happy for you. We all gotta do what we do best. But to say "you gotta stand to make a difference", I don't think that is accurate. In the end, as with most stuff we discuss here, it's a preference thing, and it's what makes us all unique as musicians..Brian
