Nuts, they only have an 8-ton weight at the theater, but I think it will work, anyway.
The real bummer is that we won't have the grand piano on stage. Paul is (rightfully) worried about damaging it in lifting it onto the stage from the backstage area. (we did that once for a game - got about eight people around it and lifted that behemoth up there) But the practice piano will be there, so I will still be able to bust out some Chopin and Gottschalk on my unsuspecting players. It will drive them mad, MAD!, I tell you. Muahahhahhaha!
