I'm going, can't wait! My parents shelled out for tickets for all of us but it was £45 each plus booking fee as far as I know - I don't think that's bad at all, given the price of gigs these days - I've shelled out around 3/4 of that for much shorter gigs at London venues - this is Iron Maiden doing a 2 hour set plus 3 or maybe 4 supports (I forget the exact line-up), doors open mid afternoon - so you're getting more for your money than an evening only do. Compared to some of the prices I've seen recently this is a bit of a bargain!
