Haha if she wasn't playing Glasto now then we are looking bad lol. Roll on Ed, Rihanna and Sam lol. My ticket probably wouldn't go back in the pot but if they failed to book The Prodigy as well....an Other slot for me that got away then I could genuinely see me missing out not be an issue.
Whilst I get your point, I think people have a right to complain if a Disney pop star is headlining a festival called Rock Werchter. I know it's a point which comes around annually and they can only book what's available but it's obvious that this would be a booking that divides opinions.
(Please note I am just playing Devil's Advocate, I don't mind either way because I don't know enough of her songs. I thought Driver's Licence was a great song, thought Vampire was absolute whiney trash. Will give her a listen a bit more but I imagine it's a definite ticket seller of a booking either way)
