Leeds gig ticket stub, neon yellow with barcode

Found a printed concert ticket this afternoon around 2:15pm outside the O2 Academy Leeds on Cookridge Street. It's an A6 paper ticket, neon yellow with a purple border, and the big barcode at the bottom is still clear. The event name is partially legible—looks like 'Live Nights'—and the date printed is 'Fri 12 Jul'. There's a small blue sticker with the initials 'MF' stuck to the corner, and the paper is lightly creased from being in my jacket pocket. I know tickets like this can have sentimental value or be a gift, so I’d really like to get it back to the rightful owner. If you recognize it, message me and we can arrange a safe handoff.
