Heather Mitchell's mainstage debut was more than 40 years ago and she continues to delight audiences, last year performing to full houses in a one-woman show at the Sydney Theatre Company. Now, Heather has written a very tender memoir called Everything and Nothing.

Also, we hear the opening scene of Pony, a frank and funny play about the wild ride of pregnancy and childbirth, and we mark the passing of improvised theatre pioneer Keith Johnstone with Lyn Pierse, author of Improvisation: The Guide, and Adam Spencer, host of the upcoming TheatreSports All-Stars at the Sydney Comedy Festival.
