I have 2 x Mumford and Sons tickets, Tuesday 18th December, O2 arena, London. £120 for the pair, seated next to each other in block 408. Much cheaper than Viagogo! The concert is sold out, and the band are going on a break after this tour so will be the last chance to see them for a while!
Tickets are in hand. Exchange in the London area asap.
Face value: £80
