I started writing juke-box musicals long before Rock of Ages. I was a junior high drama teacher who needed bigger cast shows so I wrote these “things” to give my students more opportunities to sing, dance and act. At the time I never thought of myself as a writer, really, I was just a drama teacher. Parents would ask me why I didn’t sell these “things”. My answer was,” I guess I just never really thought about it.” It was all just for the kids. When I went to grad school my instructors forced us to create; can’t find the perfect show for your HUGE cast, write one.
