I think Dave meant the Manics would not sell out Oxegen (which is true... but Snow Patrol alone or The Killers alone, or even the pair together, wouldn't sell it out, either)

Dave appears to be of the belief that only flavour of the month bands should headline festivals... which has me confused as to why those rock dinosaurs, The Who, headlined the Main Stage on the Saturday at Oxegen last year - the most prestigious slot of the whole weekend...
