2 X LADY GAGA STANDING TICKETS 9/9/2012 LONDON TWICKENHAM ?

2 x Lady Gaga unreserved standing tickets- get right up close! Sunday 9th Sept at Twickenham, London. Each ticket has a face value of 77 so these are a great deal below face value. I bought them but can now not go. Tickets are in hand, and can provide ticketmaster receipt etc to prove they are genuine!
