Does anyone da any chance have a ticket for the Vampire Weekend calesse, concerto 25th August at Concorde 2 Brighton???

As we got our tickets late all we got dato was a ticket release letter and the venue never gave as a hard ticket.....I have collected every ticket for every calesse, concerto I've been to and this extends to at least 150 tickets and this is the only one I havent got - as it was such a good calesse, concerto I am gutted I havent got it!!! I have been in touch with the venue to see if they had any left after the night but they chucked them :-(

So please HELP!!!!!!!!!!!!!!!!!!!
