Just spotted an Ozzfest in the O2 arena for September 18th.  So far the following bands are playing:  Ozzy Osbourne, Korn, Murderdolls, Skindred.  Lots more bands to be announced, two stages. I have bought my standing ticket.  https://www.ozzfest.com http://www.o2blueroom.co.uk/events/Ozzfest-2010/383
