LA JOLLA — La Jolla Playhouse, renowned for sending musicals to Broadway, revealed this week titles and dates of all but two musicals for its 2011-12 season. A total of six will be shown. Announced thus far are a co-commissioned production of Kirsten Greenidge’s “Milk Like Sugar;” the world premiere of Arthur Kopit and Anton Dudley’s “A Dram of Drumchhicit;” an adaptation of Henrik Ibsen’s “Peer Gynt;” and Richard Montoya’s “American Night: The Ballad of Juan Jose,” created for Culture Clash. Playhouse artistic director Christopher Ashley said he’s delighted to stage Kopit’s Playhouse debut. The playwright is the author of “Oh Dad, Poor Dad, Mama’s Hung You in the Closet and I’m Feelin’ So Sad” and “Wings.” He also wrote “Nine” and “Phantom,” both of which feature music by Maury Yeston. Kopit and Dudley’s “A Dram of Drumchhicit,” however, is not a musical. It’s a comedy about an American entrepreneur who sets off to build a golf course on a Scottish island, only to discover the land is rife with secrets of the supernatural kind.
