A chamber opera called "The First Lady" is in rehearsal. Roudebush, one of the work's creators, sings the small but affecting role of the priest who officiated at the White House funeral of Franklin D. Roosevelt.
The funeral scene is drenched in operatic grief, and the irony is not lost on Roudebush. Twenty-two years ago, doctors advised him to quickly get his affairs in order, take a last trip to Europe and plan his own funeral.
Friends remarked on Roudebush's pallor in August 1988, but it wasn't until late November that he wrote in his diary: "Up early and did laundry. Alarming pounding of heart and weakness in legs climbing stairs."
Despite the symptoms, he drove to the Napa Valley from Los Angeles to spend Thanksgiving with his brother and sister-in-law. She whisked him off to a doctor. Tests revealed that he was inexplicably anemic.
The doctor advised Roudebush to check in to a hospital immediately. But there was one problem: He had a ticket the next night to see Dmitri Shostakovich's "Lady Macbeth of Mtsensk" at the San Francisco Opera, and he wasn't about to miss it.
The day after seeing the opera, Roudebush made the six-hour drive back to L.A. alone and went to the emergency room at Kaiser Permanente Panorama City Medical Center. The doctor on duty took one look at his blood-test results and admitted him. A colonoscopy found a tumor the size of a tennis ball. He needed surgery right away.
But there was one problem: Roudebush had a ticket to see Los Angeles Opera's production of Alban Berg's "Wozzeck." He wasn't about to miss it.
Roudebush, 62, developed a passion for arias and libretti at an early age. His parents' tastes ran to Chubby Checker and Fats Domino, but Roudebush couldn't get enough of 78-rpm recordings of the coloratura soprano Amelita Galli-Curci and tenor Tito Schipa. His father, who laid linoleum floors, would not allow his son to study violin, saying it wasn't practical.
At Culver City Junior High, he befriended Kenneth Wells, a classmate from a musical Baptist family. (Wells' grandfather, Clarence Wells, was choir director for evangelist Aimee Semple McPherson's Angelus Temple in the 1930s.)
Wells had begun plunking away at an untuned honky-tonk piano at age 9. He started composing at 12 and later formed a gospel singing group. For his 13th birthday, his father brought home an "as is" Hammond organ that they repaired. His father installed a speaker in a wall so that neighbors could hear the boy play. Occasionally, someone would knock on the door and request "Lady of Spain."
"We'd go Christmas caroling as a family and sing in 16-part harmony," said Wells, 61, now a psychiatrist, professor and researcher at UCLA and a senior scientist at Rand Corp.
As their classmates grooved to the Beach Boys and Motown, Roudebush spun for Wells his recordings of Joan Sutherland, Maria Callas and other opera greats.
After high school, Wells went to Occidental College, then to medical school at UC San Francisco and finally to UCLA, where he earned a master's degree in public health.
Roudebush took a different path, studying English at California State College at Long Beach and working at his father's hardware store. They attended an occasional recital or opera together.
The usually reserved Roudebush was fearless about going backstage. After one performance, the two presented themselves to Sutherland and a rising star named Marilyn Horne. When Sutherland asked whether they sang, Wells replied that he was a tenor.
"Here is a tenor you should meet," she said, turning to her left. "He is going to be famous someday." It was Placido Domingo.
The friends lost touch for a time, but in late 1978, Wells enlisted Roudebush for a new choral group, later dubbed the Mansfield Chamber Singers.
