Pair of concert tickets with VIP backstage pass

I found these this afternoon around 3:50pm outside Norwich railway station, near the main entrance on Prince of Wales Road, by the bus stop. They're two glossy A6 concert tickets for a gig at a venue nearby, printed on white stock with a barcode along the bottom. One ticket has a small coffee stain in the corner and a red star sticker on the back with the initials 'LB'. The other ticket is pristine, with a handwritten note on the back that reads 'For Leo'. The backstage VIP pass is attached via a small red lanyard. I’m sharing here because they clearly belong to someone who’s excited to go see the show, and I’d love to get them back to their owner.
