Thanks for the info. Usually you can guess what the requests will be but I hate it when someone feels they have to play "Stump the musician" and there's always one drunk who does that. Then you look like the bad guy because you can't do it.
One other question. Your setup is the most novel thing I've seen in years. Who made the piano shells? Doing curves like that takes some skill and the finish is very nice.
I've seen companies online that make dummy case but your idea of the folding tables is unique.
Put up some more pictures and maybe some songs.
