A short word from my good podcasting friend Peter Schmitz, he of the ‘Adventures In Theatre History Philadelphia’ podcast, who has written a book on that very subject and I’m sure that it will be as informative, as amusing and generally as fascinating as his podcast episodes always are. What is even better is that Peter has produced a short audio that gives you all the information you need about the book and how you can get hold of it. These links might be useful:
