I've got one ticket on box office collection for Grimes on Wednesday. I've decided to see Cloud Nothings at The Cargo near Old Street instead that evening. I'm sure I can show the box office my credit card/email confirmation etc. and allow someone else in, instead of me. I'll just then turn around and go to my other gig. Anyone fancy it? Oh, the ticket is free by the way; I won't be using it.
