Dave, if you believe that standing during a 4-hour performance V/S sitting burns that many more calories, then you should be skinny as a rail. According to those studies, if you stand all day long, you would burn an extra 54 calories, which is equal to about 1 French fry.

You would probably burn at least 54 calories just by shifting your left hand on the keyboard about 20 times. Gimme a break!
