Might get a day ticket for Iron Maiden, but the rest of the line-up is pretty stable festival fodder (apart from maybe Alice Cooper, who I don't know if his show will transfer well to a festival stage).
I've already got my ticket for next year's Download Festival. If the rumours are to be believed, then that is likely to have AC/DC, Metallica and somebody else as headliners (Pearl Jam and Bon Jovi are rumoured for the third slot).
The good thing is that there are now two rock festivals competing for ticket sales, so hopefully they are going to be making sure that there are great bands at both festivals.
