The Gilbert and Sullivan Light Opera Company of Long Island a desire to try new projects and convinced that it had been depending too much upon “the Big Three,” the Company undertook a complete cycle of the works of Gilbert & Sullivan, beginning with Princess Ida in 1992 and concluding in 2004 with The Mikado. The Project, which has been an overwhelming success, has featured the Long Island premieres of four operas—Princess Ida, The Yeomen of the Guard, Utopia, Limited and The Grand Duke, as well as of the Sullivan/Stephenson operetta The Zoo. In 1995 the Company presented the world premiere of Gayden Wren’s A Gilbert & Sullivan Christmas Carol.
The Mountebanks work was released in 2018. The story of the opera revolves around a magic potion that transforms those who drink it into whoever, or whatever, they pretend to be. The idea was clearly important to Gilbert, as he repeatedly urged his famous collaborator, Arthur Sullivan, to set this story, or a similar one, to music. For example, he had written a treatment of the opera in 1884, which Sullivan rejected, both because of the story's mechanical contrivance, and because they had already produced an opera concerning a magic potion, "The Sorcerer" (1877); Sullivan felt that the story lacked "human emotion".
