Horizons is extending "Orgasmo Adulto Escapes from the Zoo" through Sunday. Last week, lucky patrons were awarded door prizes donated by the Pleasure Chest, a Georgetown sex boutique. We won't say what they were . . . Stephen Kennedy of Columbia, Md., won the Source Theatre raffle, which raised $3,000 for the theater. Kennedy won a trip to Los Angeles, all expenses paid . . . The Acting Co. will perform "As You Like It" at a benefit March 4 in the Terrace Theater. The $50 ticket includes supper after the show with John Houseman and other alumni of the company . . .

The National Music Theater awards were presented last week to Stephen Sondheim and James Lapine for "Sunday in the Park With George," and Lee Breuer and Bob Telson for "The Gospel at Colonus." Grants ranging from $2,000 to $10,000 were awarded to gold medalist David Malis, silver medalist Alteoise Devaughn and bronze medalist Louise Edeiken (who studied at George Washington University).

Advance sales for "Godspell," returning to Ford's Theatre March 8, have already topped $300,000 . . . American National Theater watchers note: The cast of "Henry IV, Part One" is filled with musical comedy veterans rather than Shakespearean types. Bruce McGill and Denny Dillon were in "My One and Only," Tony Azito was in "The Pirates of Penzance," Patti LuPone was the first "Evita" and Jossie de Guzman was in "West Side Story." Falstaff will be played by David Huddleston, who played the neighbor in the recent "Death of a Salesman" production that starred Dustin Hoffman.
