Revues are often common today as student entertainment (with strong traditions in many universities in UK, Canada, Australia, New Zealand, Norway and Denmark). These use pastiche, in which contemporary songs are re-written in order to comment on the college or courses in a humorous nature. While most comic songs will only be heard within the revue they were written for, sometimes they become more widely known—such as "A Transport of Delight", about the big red London bus, by Flanders and Swann, who first made their name in a revue titled "At the Drop of a Hat".
