About the year 1834, when the earliest of the Sketches by Boz were appearing in print, a young composer named John Hullah set to music a portion of an opera called The Gondolier, which he thought might prove successful on the stage. Twelve months later Hullah became acquainted with Charles Dickens, whose name was then unknown to those outside his own immediate circle, and it occurred to him that he and 'Boz' might combine their forces by converting The Gondolier into a popular play.
