Infinitely more lovable than Jonathan Ross, a shiny-suited Norton welcomes another four guests to his boisterous Friday night chat show. Gavin and Stacey's James Corden will be insisting we take him seriously following the stellar run of One Man, Two Guvnors at the National. Expect a torrent of jokes as fellow comedian Sarah Millican and Bradley Cooper of The Hangover Part II will also be vying for attention on the red sofa, while rock star Lenny Kravitz performs.
