Pop veteran Sir Cliff Richard has quit the pin-up parade and announced he is not going to release another of his best-selling calendars. The 2014 calendar has an American theme with pictures of Sir Cliff wearing cowboy boots perched on the bonnet of a car and another of him walking down railway tracks with a guitar on his back. He has told chatshow host Graham Norton that it would be his last. He said: 'I am not going to do any more. How many shapes can I pull with this body? It's a pressure.'
