Albert Bergeret, founder and artistic director of the New York Gilbert & Sullivan Players, can boast of having either conducted, directed, designed or sung in every production in the company's 40 years. He has built a devoted audience for his company's broadly humorous stagings. Next up is this revival, which begins a six-performance run on Friday. Wednesday's performance is a special New Year's Eve gala, with a little bubbly promised at intermission.
