I am one who sits when he plays. I agree with Schmange that you'll certainly look better moving, dancing, giving body English, what ever. If ou can do this without effecting your playing you'd be much better off. The other's in my band stand and play, but I sit because I play a lot better that way. I'm the best guitarist in my group and I like to really concentrate on what I'm doing. I agree, I probably look like a turd on stage, but that's just the price I have to pay for playing at my best.
