Exactly 20 years ago, Serge Gainsbourg bought the farm, as the Americans like to say. In 1962, he had written Requiem pour un twisteur, la danse du Twist being “the greatest ritual since circumcision” (Leonard Cohen) in those early Sixties. The song was, in Serge’s own words, “about a guy who twists himself to death”, but certainly it was also a song about life. A Gainsbourg one. Only the dance fashions had changed a bit through the years.
