You may be right. On the flip side, I was at the Docklands gig back in the day and most of it was just lost on the wind. Indoors with lights/lasers could be quite something...I just hope that with that many people rammed inside a small venue we don't run out of oxygene.
Uncle for someone whose cultural taste (music/film) is barely on a par with that of a prepubescent girl (East 17s Stay Another Day a noteworthy exception) I have to say you've hit the spot with this one. Will be an amazing wall of sound in a venue that small. More power to Haven Home Loans...
