It was the men in white shirts that we objected to, one in a chair right of stage who seemed to be asleep half the time and up to 2 others who frequently stood to the far right of row U, where we were seated, who permanently looked ready to pounce - on whom, for what?? There was also a very angry looking man either in a black suit or black shirt who was moving about all the time, whom we found most intimidating and a distraction.

That said, the concert sound was of the best I have ever heard anywhere.
