Mark's response was very impressive; he kept his cool and was patient. Not like in Toronto 2008 - I was in the front row with my wife (her first front row experience), and towards the end of the first song, Cannibals, I believe, he pointed to the right side of the amphitheater, and was visibly angry with the flash. I am sad to say, that this ruined the entire rest of the concert, in that Mark was never himself from that point forward. I even sent an email to Guy to express my frustration, bring that we flew from New York just for the show.
As I expected, he never responded:)
It was especially disappointing since in 2005, I had front row center in NJ, and Mark and I communicated a number of times during the show, which to this day make it the best MK experience I had since meeting and talking to him after his David Letterman appearance (in 2003 I think, before his motorcycle accident) !
