When Miles Jupp appeared on Richard Herring’s Leicester Square Theatre Podcast, he got a big laugh when he said that the host was getting to the point where he has “no unpublished thoughts”. In addition to a rigorously updated daily blog and a weekly Metro column, Herring has in recent years maintained a variety of eccentric podcasts – including live sketch show As It Occurs To Me and the bewildering Me1 vs Me2 Snooker, where he commentates on games that he plays against himself. The Leicester Square Theatre Podcast sees Herring sharing the limelight with a succession of big figures from the world of comedy, who are subjected to interrogations that are alternately very silly and oddly revealing. Previous subjects have included Armando Iannucci, Russell Brand and Herring’s estranged double-act partner Stewart Lee – this week’s guest is Bob Mortimer.
