2 x Ben Howard 29th Nov Brixton tickets to swap for 30th Nov !

Hi, I have 2 standing tickets for the Ben Howard gig at Brixton Academy on Thursday 29th November. Unfortunately I can no longer make this date so I am looking to swap them for 2 tickets to the show on Friday 30th Nov. (or even just swap 1 of mine for 1 on the 30th). Please let me know if you can help me out! Thanks, Rachel ps. I am only looking to swap these tickets, not sell them, I just had to put a price in for gumtree
