The play is owned by Marilyn Abrams and Bruce Jordan. Shear Madness is among the longest-running non-musical plays of the world, the play is placed in a unisex hair salon in the city. The landlady, Isabel Czerny, who lived above the shop, was murdered and the audience got involved in the action by questioning the actors and attempting to solve the crime.
The characters contain a flamboyant homosexual hairdresser and his flirty yet ditsy assistant, along with a stuffy and proper tense older lady and an older man who is a "used antique dealer." Much of the dialogue is unrehearsed by the actors, and the humor tends to revolve around current references to current events.
The ending of the play is unusual every night as audience members hear clues, question the characters and then vote on who they think is in the wrong. Shear Madness started in Boston at the Charles Playhouse Stage II in January inn the year 1980. A second production opened at the John F. Kennedy Center in Washington D.C. in August the year 1987. The Boston production is sometimes determined as the second-longest-running non-musical play in the world, even though various non-musical plays have run for longer.
