They were invited by David Frost to appear in his new show, The Frost Report, with John Cleese, but the pair's big break came when they filled in, unprepared and unscripted, for eleven minutes during a technical hitch at a British Academy of Film and Television Arts awards ceremony at the London Palladium in 1970. In the audience was Bill Cotton, the Head of Light Entertainment for the BBC, and Sir Paul Fox, the Controller of BBC1. Cotton was so impressed by the duo that he turned to Fox and asked: "How would you like those two on your network?"
