peter: (this may be a dumb question but that's never stopped me before) at the end of the "amplifier" video, is that a real piano or a dummy? i must know. either way, a brilliant move having your two mates "hold" it up while you play the outro.

That was a styrofoam piano, built, along with all the other cool props, by Jim Wilson. Jim's most legendary creation until that time was the Burger King grill which propelled the cooking burgers over the fire in the commercials. Jim's a friend of the director's, Walter Williams.
