Peter Langan was the first bad-boy celebrity chef. Hockney painted his portrait and in his career as a restaurateur and London's most notorious drunk he became more famous than most of his customers. The time his kitchen caught fire in 1978 he reportedly sprayed the flames with champagne while waiting for the fire brigade. Regulars included Billy Joel, Christie Brinkley, Grace Kelly, Princess Stephanie of Monaco, Donald Sutherland, Sean Connery, Mick Jagger, Lauren Hutton, Elton John, Bob and Paula.
