>My favorite marching band instrument was in an old Woody Allen movie. He marched a big ole bass. Had the bass in one hand and a chair in the other. He'd run up 2 steps, sit down, play 3 notes. Then pick up the chair, and repeat the steps all over again in a couple feet.

I own an Upright and thought it would be funny to put a wheel on the bottom and march it. Not very load though < s >
