The Gilbert and Sullivan Light Opera Company of Long Island a confirmed Savoyard. He’d served as vice president of the New York Gilbert & Sullivan Society, and even produced a televised version of The Mikado in 1949. When Helen Marx, president of the Camp Avenue School PTA, asked him if he could organize a fundraiser, his thoughts turned—as they so often did—to Gilbert & Sullivan. Initially the idea was for Packer and Waters to run an adult-education class in G&S that would culminate in a performance of The Mikado. But when Packer recruited an old friend, Sally Buckstone of Oceanside, to sing, the seeds of a new group were planted.
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".
