Hilarious Voyage with "Pirates"

Amid the plethora of Harvard’s arts offerings, it might be easy to take the Harvard-Radcliffe Gilbert & Sullivan Players for granted. Year after year they mount solid productions of Gilbert and Sullivan’s comic operettas, typically eschewing gimmicks or eccentric stagings in favor of period costumes and a classic good time. Their new production of “The Pirates of Penzance; or, The Slave of Duty,” which runs through Sunday in the Agassiz Theater, demonstrates the very best of this approach.
