Yes.
I figured it out last time. When I was there they played TWO announcements. The first said no flash/external video lighting. The second was the ORIGINAL pre-recorded announcement, which said "for the safety of our performers, there is to be no photography or videotaping". Last time I checked it wasn't hazardous to be filmed doing something with no flash/lighting. So let me fix what they meant:
"For the safety of our performers' contracts, there is to be no photography or videotaping"
The original cast is long gone.
