Every summer the Capital Hill Arts Workshop presents a different Gilbert and Sullivan production in partnership with the GLBT Arts Consortium. This year brings a slightly modern twist on the classic HMS Pinafore, with the Royal Navy being usurped by the Department of Homeland Security in manning the ship. But classic tales and tunes, including "When I Was A Lad" and "I'm Called Little Buttercup," are still part of the show, directed by Peter DiMuro and Barbara Schelstrate. Net proceeds benefit CHAW and the Consortium. To Aug. 13. CHAW, 545 Seventh St. SE. Tickets are $20. Call 202-547-6839 or visit chaw.org.
