I believe the most taped show is that one in Rome. The security only checked for water bottles. You couldn't enter the palace with them or at least you had to detouch their stoppers but... strangely normally closed bottles were sold inside the palace.
I saw at least 5 video-cameras on the "Brian" side of the stage, I think there were at least other 5 in the middle and 5 on the left.
It's hard to say if they will be released somewhere but I think in few days you may have something...
