The play is a musical reconstruction of incidents relating to the East End murders which took place between Friday, August 31st and Friday, November 9th, 1888. A solution of Jack the Ripper's identity is hinted at, but the play is an atmospheric commentary rather than an historical re-enactment, shifting between reality and artificiality, with characters representing "real" people as well as members of the music hall audience and players. It is an essential feature that some characters are called upon to play more than one role. They thus have a life within the Music Hall and also in reality. The Chairman also plays the authoritative roles of Sir Charles Warren, the Magistrate, and the Dock's Foreman, while Montague Druitt is also known as Toynbee and plays the villain in the melodrama, and the magician. Vocal score on sale. Perusal material available.
