Looking to swap 2 or 3 10th Feb Black Keys Tickets for 9th or 11th Feb (Straight Swap) .

I have 3 tickets for the Black Keys concert at Ally Pally on the 10th Feb but can now not attend, so was looking to go to the concert on the 9th or 11th Feb. If only 2 tickets to swap then thats fine, can sell the third. Thanks
