Theatre Restaurant Style plays are popular often with significant audience participation. They often based on well known stories.
CRACULA's CASTLE has been very succesful. I have seen two performances at different locations. It is based on a combination of Rocky Horror Show and Dracula. All the guests (audience) are at risk of succumbing to Cracula's powers and end up as vampires but fortuneately a way of destroying those powers is found just in the nick of time- or is it? Several songs of the director's choosing can be incorporated. There are 5 male parts and 4 female, one of whom doubles as a waitress. Musicians, who don't need to actually play anything can also be incorporates as can real musicians
