These days, buying concert tickets is a huge expense. If fans miss out, they can often find tickets on resale sites at hugely inflated prices. Sometimes people resell their tickets because they can’t go but there are also lots of “professional resellers” or ticket touts playing the system and making loads of profit. They buy tickets in bulk from the original seller platform, then mark them up to fans.

We hear from a Taylor Swift super fan, who has spent hundreds on resale tickets.

Now, a group of musicians including Dua Lipa, Coldplay, Sam Fender and Radiohead have sent a letter to the UK government, asking politicians to introduce a price cap on resale tickets to "stop touts from fleecing fans”. Ireland has already introduced a law to stop people selling tickets for more than their original price. Gary Devitt, who co-founded a platform in Ireland for fan-to-fan ticket resales called Toutless, gives us his view on what effect the law has had.

In this episode we hear some stories about buying resale tickets, and ask whether price caps can actually stop the touts. The BBC’s music correspondent Mark Savage also explains how ticket touts operate, and what artists could do themselves to reduce dodgy reselling.
