Television viewers have already been treated to Ray Stubbs 'singing', Shaun Williamson belting them out and Tara Palmer Tomkinson exercising her tonsils in Comic Relief does Fame Academy. Also a clash of the celebrity egos are put through their paces by Sir Alan Sugar in a special edition of The Apprentice including Piers Morgan and Alastair Campbell for the boys team and Trinny and Karren Brady for the girls.
