Awww, yer man Denis Norden really is gone. Well, he was doing it for 30 years. The 86-year-old (who wrote his links himself, eat your heart our Martin King) has handed the reigns over to comedian/actor/writer Griff Rhys Jones to presents this new one-off special. Tonight's show sees favourite duo Ant and Dec in a muddle on Saturday Night Takeaway, This Morning's Fern Britton and Phillip Schofield dissolve into fits of giggles (for a change) and Dame Helen Mirren redefines the Queen's English when she drops a clanger on live TV. Plus there's There's unplanned comedy from The Green Wing and Nighty Night when the cast play some on set pranks and the scenery takes on a life of its own. Of Griff stepping into his shoes, Norden graciously said: "I wish Griff every success with his outtake hunting and hope he'll enjoy at least another 29 years on the show - but he's not having my clipboard."
