[citation needed] In 2009, Peterson and Gray returned to their roles at Soulpepper Theater in Toronto, in a re-mounting where Bishop tells his story, wearing pajamas and dressing-gown, near the end of his life.
[citation needed] Gray has written and composed six other musicals including 18 Wheels, Rock and Roll, Don Messer's Jubilee, Health, and Amelia: The Girl Who Wants to Fly (2011).
