Hey, I've got my Sufjan tickets from Southbank posted through to me now, but in a panicky-make-sure-I-get tickets, I bought two pairs for Friday 13th May (one pair over the phone/one over the internet), and I just need one pair.
Anyway, I have two tickets for sale to whomever would like them, and is able to meet up in central London at some point. £50 for the pair. Don't be a tout/go selling them on ebay though, or I'll be sad. They're for the third row on the balcony.
