Each Halloween Season, many horror and science fiction offerings hit our stages. This year, David P. Johnson is bringing his Sally Spectre: The Musical back to Theatre West weekends through October 29. A combination horror and morality play, it centers around the ghost of a 5-year-old girl trying to escape from her locked bedroom where she was brutally murdered. But is this musical really for children? To find out, I decided to speak with David P. Johnson who not only wrote the book, music, and lyrics but also directs and co-produces it, and appears onstage accompanying the cast on keyboard during every performance.
