In the fourth show Alan is joined by Eddie Izzard, who talks about his role in the new Pixar film Cars 2, while Chris Moyles pops in to discuss about his new series of Chris Moyles' Quiz Night (which also happens to be shown on Channel 4). Alan is also joined by Professor Brian Cox (for some reason), and indie-rock band Hard-Fi perform in the studio. Hard-Fi, from 2007(ish), kind of rubbish? Lots of haircuts. There ya go. If you'd like to see a camp host presiding over celebrities who aren't quite as subtle regarding the peddling of their current wares, there's Wall of Fame over on SKY1 at the same time. David Walliams is joined by regulars Kate Garraway, Andrew Maxwell, Jack Dee, Tamara Ecclestone and celebrity guests on the topical panel show focusing on some of the world's most talked-about people.
