I know you're not really allowed to do this, but I've got a Glastonbury ticket that I can't use anymore.
It has my photo on it, but if you are a girl with blonde hair, you should get away with it. Even if you're a girl with dark hair, people use hair-dye. For the past two years, I haven't even seen a glance at the photo when it comes to the ticket exchange. And it makes clear on the Glastonbury website that you don't need to bring any form of ID with you.
The face value of the ticket is £175, but I'm happy to sell it to somebody for £110 or nearest offer. I really want to get rid of it, it'll break my heart if it just sits redundant over the Glastonbury weekend...
