A dedicated family man, he is married to soprano Nancy Stokes. The couple has a 6-year-old son, Shawn, and Milnes has two other children from a previous marriage. He has been a Westsider for almost 10 years. Not at all snobbish about his own musical gifts, Milnes believes that singing is excellent recreation for anyone, regardless of voice quality. "I encourage people to sing in the shower. It's a great emotional outlet. Even if you're lousy, it makes you sound fantastic. When I'm on the stage, I always have that feeling that I'm never going to sound as good as I do in the shower. You can't get the same _ring_ when you're singing to 5,000 people." ******** WESTSIDER CARLOS MONTOYA Master of the flamenco guitar 10-28-78 Carlos Montoya speaks two languages. The first is music; the other is Spanish. At 74, he is the world's most famous master of flamenco -- the ancient folk music of the Spanish gypsies, which Montoya performs with dazzling speed and dexterity. On October 29 he will give a major concert at Avery Fisher Hall. With more than 30 albums to his credit, Montoya is the most recorded flamenco guitarist in history. He is thoroughly committed to his instrument. It is not merely his living, but his life. He is a pure gypsy -- "on all four sides," as the Spanish say. Maybe that explains why he likes to tour from January to May and from October to December every year, almost nonstop, across the U.S. and Canada, to South America, Europe and the Far East. He has been a Westsider since the 1940s and has rented the same Westside apartment since 1957. Yet when people ask Montoya where he lives, he is likely to reply, "On airplanes." An American citizen for more than 30 years, he is perhaps the first persons ever to acquire citizenship after answering "no" to the question, "Do you like the American form of government?" Because of his poor English, he had misunderstood the query. He corrected himself, and that night played for President Harry Truman. Montoya's wife, Sally, is his steady helpmate. Since their marriage in 1940, she has been his manager, interpreter and best friend. He still speaks little English, so interviews with him are often ponderous three way affairs. When I arrived at the Montoyas' residence late one morning, he was very polite, but eager to get the interview over with. "Vamos," he said. His demeanor changed when he discovered that I was able to understand his crisp, precise Spanish when spoken slowly. We quickly dispensed with the interpreter.
