Gilbert and Sullivan had a knack for mocking issues that still provoke rage, including Darwinism, feminism and a host of other -isms. And that goes for the operetta "Princess Ida," which will open the Lamplighters Music theater's 60th season in Walnut Creek on Jan. 25.

The story, a crazed dash about what was on English minds in the 1880s, is set, um, somewhere, since G&S indicated neither a time period nor a location for the show. But it does offer some interesting notions, beginning with a treaty, signed 20 years before the play starts, stating that Princess Ida and Prince Hilarion will marry when they come of age.

But the princess, now the founder of a women's university, will have no part of an agreement that was signed when she was an infant. Instead, she will continue teaching an unusual variation on Darwinism -- that men, but not women, are descended from the apes, making women superior to men.

But Prince Hilarion is ever the romantic, so he decides he will woo the fair maiden by donning the academic garb of the university (drag, in Hilarion's case) and enter the school as a student.

"Ida" plays Jan. 25-27 at Walnut Creek's Lesher Center for the Arts, then it goes to San Francisco's Yerba Buena Center for the Arts on Feb. 1-3, the Bankhead Theater in Livermore on Feb. 9-10 and the Mountain View Center for the Performing Arts on Feb. 16-17.
