Seriously, IF this CAN be enforced for this show, why can't/won't it be done for EVERY show? Does it come down to it being done only because a specific performer/producer wants it to be done? Is it that the logistics/cost are more than other producers are willing to deal with?
Anyway, it would be wonderful if it became widespread.(O.K. I've opened the floodgates: let's hear the outcries against this.)
