They weren't exactly subtle about saying that either. So, yeah, they're not coming back, plus it looks like they're playing the mainland over Glastonbury weekend anyway.
In a word; no.
Last time Glastonbury tried to book them they were “insulted” with the “low” financial offer.
First few albums brilliant but they really fell off and expect the world. Had to cancel loads of their tour last year because they over estimated their popularity.
