The Rocky Horror Picture Show {RELEASED 1975} originally started out as a stage play called The Rocky Horror Show {RELEASED 1973 - LONDON}. The stage show was mounted in a tiny 60 seat experimental theater called The Royal Court Theater Upstairs.  Designed to look like a run down movie house under renovations, the set offered the opportunity to get the action off the stage and in and around the audience, with people making entrances and exits in the most unlikely places.  Climbing up scaffolds or romping down ramps. Dancing in front of the 'movie screen' or having shaddowplay behind it.  There were no Transylvanians in the original stage show, just a few creepy phantom ushers lurking about in the shadows.  The opening number, 'Science Fiction' was sung by an usherette {FOR THOSE OF YOU WHO AREN'T OLD ENOUGH TO REMEMBER REAL SERVICE IN A MOVIE THEATER, ASK YOUR PARENTS WHAT A VENDING USHER OR USHERETTE IS}, who later in the show also played Magenta.  All in all, a much different animal than the movie version.  Although, the Rocky Horror Picture Show Phenomenon of performing and audience participation brings some of this all-encompassing performance back to the piece, it just doesn't compare to the raw tacky exuberance of the original format of the original stage play.
