Gorilla Repertory Theatre Company, the Manhattan company known for site-specific stagings, sets a revival of Gilbert and Sullivan's comic operetta classic, The Pirates of Penzance, aboard a three-mast shop, The Peking, for a run Aug. 4-28. Docked at the South Street Seaport Museum, the Peking remains in port for the show, which officially opens Aug. 6. Performances run Friday to Monday.

The musical yarn, about an orphan indentured by pirates, is directed by Michael Scheman. Musical direction and arrangements are by Steven Gross. Choreography is by Tony Parise.

Gorilla Rep might be best known for its annual staging of A Midsummer Night's Dream in Washington Square Park. Midsummer and As You Like It play this summer, Aug . 3-Sept. 24.

Mistaken identities, pop variations on the classic score and cross dressing all play a part in the reconception.

The cast includes Brett Colby, Annette Cortes, Alison Renee Foster, Joseph Greene, Michael Colby Jones, David Joseph, Stephen Kaplan, Rebecca Kendall, Kent LeVan, Kenny Marshall, Patrick McCarthy, Brenda McEldowney, Kristy L. Merola, John P.F. Moore, Jessica Polsky, Heather Jane Rolff, Gordon Stanley, Colin Stokes, Gretchen Weigel, and J. Michael Zally.

Tickets are $15 for all seats. Call (212) 330-8086, or visit the web site at www.gorillatickets.com or www.gorillarep.org.
