That's correct. In the audience, there were both veteran and non-veteran witnesses who came and enjoyed the theatre piece. We performed for a lot of educators in the U.K. and Australia and even here in Ottawa.
One unique thing about the play—and I'm not sure about the play you're mentioning—is that the performers themselves were also veterans. It's difficult to spill your guts and share the most traumatic moments in your life 20 times, plus rehearsals. It wasn't necessarily something that could go on forever with the same participants.
If it were to continue, my guess is that you would need different participants. Also, there should be a time cap on how long they're participating in it, because it can be retraumatizing. There is a point where it becomes too much.
