British variety theatre has been largely ignored by theatre historians, in spite of its huge popularity in the early twentieth century. Here, Oliver Double examines variety through its exemplification in the work of one performer, Teddy Brown, a virtuoso xylophone player whose career coincided with the heyday of the variety stage between and just after the two world wars. The key historical and stylistic aspects of the form typified by Brown's success included the development of a stage persona, novelty, skill, participation, a distinctive musical style, and the ability to exploit the complex relationship between variety and the other types of popular entertainment of the time, notably cinema, revue, and radio. Former comedian Oliver Double is a Senior Lecturer in Drama at the University of Kent, and is the author of Stand-Up! On Being a Comedian (Methuen, 1997) and Getting the Joke: the Inner Workings of Stand-Up Comedy (Methuen, 2005). His stand-up comedy DVD Saint Pancreas is available from the University of Kent website.
