Yeah I mean U2 is right out, it was only an article passed by, not one I actually considered to be true but so is every other tabloid option. The Cure, Foos and TOP suggest they could still demand sizeable names, definitely one of the best top 3 choices of any festival this year and the next lines down were sizeable too. They got JT, Olivia and Muse the year before and Korn subbing.
I would see no reason they couldn't get PJ and Blink the same year and I'd almost expect it.
