ROYAL ROLE: Robert Goulet launched his Broadway career playing Sir Lancelot in “Camelot.” Now he’s bringing the show to the Orange County Performing Arts Center during a national tour, this time--with a little gray in the hair--playing the benevolent King Arthur. . . . “I’ve graduated,” he joked. The show will run Dec. 21 to Jan. 3. A second week, aimed at non-subscribers, was added to meet public demand for tickets. Goulet last played the Performing Arts Center in 1988, in “South Pacific.”
