True. The Stones only did 2 shows there this year and I don't think either was ever promoted as being sold out. There were a lot of empty seats at the one I went to.
Plus I don't think they would have even had as many people as they did if they hadn't started practically giving the tickets away near the end. I got an email a week before the show about a deal where you could get 4 tickets and 4 t-shirts for $99!
