Query: I had the great fortune

to study with Keith at the University of Calgary and to work with him at the Loose Moose Theater, and it had a tremendous impact on my life. His approach to education, to theater, to life all has a very liberating effect. This book carries a great deal of his spirit. It plants a terrific garden in your mind; some of the seeds sprout quickly while others may take a very long time to grow. This is a great book, for more reasons than I can say.
