In his look at comedians who pioneered the use of radio as a medium for subversive, spontaneous comedy, Ned Sherrin examines the career of Coyle and Sharpe. Wandering the streets with a concealed microphone for a San Francisco radio station in the early 1960s, Mal Sharpe and Jim Coyle revealed the ability of radio to spread confusion, puncture civic pomposity, and expose public ignorance-as well as to entertain in a way which had hardly been attempted before. Their style went a long way towards shaping the edgy, unpredictable presentation techniques of more recent figures like Sam Kinison and Howard Stern. Producer Paul Bajoria
