It's time for a bit of politics, but that's no reason not to discuss huge, ageing wrinkly ballbags, because tonight's guest is that rarest of things (if you're a journalist or a TV commissioner) a political comedian. It's the delightfully subversive Mark Thomas. There are tales of working for the legendary Dave Allen, getting in the Guinness Book of Records, being spied on, heckling anti-abortionists, the funny side of funerals, opera-loving builders, gigging in a cattle market, trying to get trolls for all London bridges, how the police force deal with the spirit of Winston Churchill and bringing Ireland to the Apple store. You'll also find out what prompted Mark to stop working for Channel 4 and how he lost his religion. And more proof that bronze is better than silver and gold.
