For the past decade, the cut-price Rory Bremner has been wearing the arse out of a collection of celebrity impressions including - heard it before - Obi-Wan-Kenobi and Tom Baker. Worked in local radio before being given a hand up by mate Chris Moyles on his Radio One show. People-copier Culshaw has starred in Dead Ringers and has got down his Gordon Browns and Micheal Parkinsons. A mimic in a fine British tradition, just don't ask him to phone a garage for you.
