If main stage tech need to do things, maybe Lisa wants to just take on the buzzer? Or maybe the prizes? (though I think she'd have more fun with the buzzer) I could then do the other of the two.

I understand she may just want to not see the hash they make of our smooth (ha) operation, but it's an idea to keep in mind for the day, at least.

My nose will NOT be pushed out of joint by any such arrangement!!! up to and including being told to just fetch water - or heck, to go sit in the audience (and maybe I could hear the answers then).
