Thanks for all of the excellent suggestions. Pete, as this was a library it was simply a performance area that I had separated from the remainder of the room with colored masking tape. A "psychological stage" if you will.
I was a professional photographer in the U.S. Navy for five years, and I too can appreciate what goes into getting that good shot. I'm even using an audience shot from another one of my other library shows for my next mailer. By the way, the photographer for this one (my Fort Benton, MT library show) DID NOT crowd the stage.

With that said, I would never think of grabbing a microphone at ANYONE'S show and making an announcement without the proper permission. If I had known in advance that he was going to grab the mic... I would have taken over.
As you can tell, I am not an unbiased party, but I DO appreciate all of the advice. It is, after all, what I expect AND WANT from the honest members of this forum.
The show? It went great. Matter of fact, I booked them on the spot (4 shows total) for NEXT SUMMER!
I will probably use a combination of ideas gathered here for that next RARE occasion.
Anyone have any other tips?
