SITTING IN ON a rehearsal is a strange experience for the author of the book the play is based on. Words you heard in your mind’s ear forty years ago in a small attic room in the silence of the night are suddenly said aloud by living voices in a bright-lit, chaotic studio. People you thought you’d made up, invented, imagined, are there, not imaginary at all—solid, living, breathing. And they speak to each other. Not to you. Not anymore.
