Mark Steel is obsessed with sport. Obsessed! And he's certain there's a strong link between sport and stand-up comedy - risk taking, dealing with a hostile crowd, performance anxiety. In this programme he muses on his theory with the snooker player known as 'The Entertainer', John Parrott.

For this series of three programmes, he also meets sports psychologist and former figure skater, Dr. Faye Didymus; and also the former Premiership and England footballer Graeme Le Saux.

You can hear extra bits from both interviews on the podcasts, just go to the Radio 4 website.

Produced in Bristol by Karen Gregor.
