Tony Martin, the debonair baritone whose career spanned some 80 years in films and nightclubs and on radio and television, died on Friday at his home in West Los Angeles. He was 98.

His death was confirmed by business manager, Stan Schneider.

Mr. Martin’s long life in show business began in the late 1920s, when he formed his first band at Oakland Technical High School in California. He was still performing in nightclubs around the country well into the 21st century.

“Tony Martin may be his generation’s Last Man Standing,” Stephen Holden wrote in The New York Times in January 2008. The occasion was a five-night engagement at Feinstein’s at Loews Regency in New York, where Mr. Martin sang his hits from half a century earlier while dropping names of colleagues he had outlived, like Bing Crosby and Perry Como.

After a chorus or two of, say, “The Very Thought of You,” Mr. Martin would interject: “Ray Noble, lovely guy. I met him when I did the Palladium in London, and he asked me to sing that song.”
