In 1878, Gilbert realised a lifelong dream to play Harlequin, which he did at the Gaiety Theatre as part of an amateur charity production of "The Forty Thieves", partly written by himself. Gilbert trained for Harlequin's stylised dancing with his friend John D'Auban, who had arranged the dances for some of his plays and would choreograph most of the Gilbert and Sullivan operas. Producer John Hollingshead later remembered, "the gem of the performance was the grimly earnest and determined Harlequin of W. S. Gilbert. It gave me an idea of what Oliver Cromwell would have made of the character." Another member of the cast recalled that Gilbert was tirelessly enthusiastic about the piece and often invited the cast to his home for dinner extra rehearsals. "A pleasanter, more genial, or agreeable companion than he was it would have been difficult, if not impossible, to find." In 1882, Gilbert had a telephone installed in his home and at the prompt desk at the Savoy Theatre, so that he could monitor performances and rehearsals from his home study. Gilbert had referred to the new technology in "Pinafore" in 1878, only two years after the device was invented and before London even had telephone service.
