Dolly Parton, left, sings Someone

Nashville, Tenn, ? Porter Wagoner, the rhinestone-clad Grand Ole Opry star who helped launch the career of Dolly Parton by hiring her as his duet partner, died Sunday. He was 80.

Wagoner, who had survived an abdominal aneurysm in 2006, was hospitalized again this month and his publicist disclosed he had lung cancer.

Wagoner’s illness came after a comeback that saw him recording again and gaining new fans even as he reached his 80s.

In May 2007 he celebrated his 50th year in the Opry. After years without a recording contract, he also signed with ANTI- records, an eclectic Los Angeles label best known for alt-rock acts like Tom Waits, Nick Cave and Neko Case.

The CD “Wagonmaster,” produced with Marty Stuart, was released in June 2007 and earned Wagoner some of the best reviews of his career. Over the summer, he also was the opening act for the influential rock duo White Stripes at a sold-out show at New York’s Madison Square Garden.

The Missouri-born Wagoner signed with RCA Records in 1955 and joined the Opry in 1957. “It’s the greatest place in the world to have a career in country music,” he said in 1997.

His showmanship, rhinestone suits and pompadoured hair made him famous, with his own syndicated TV show, “The Porter Wagoner Show,” for 21 years beginning in 1960. It was one of the first syndicated shows to come out of Nashville.

To many music fans, though, he was best known as the man who boosted Parton’s career. He had hired the 21-year-old singer as his duet partner in 1967, when she was just beginning to gain notice through songs such as “Dumb Blonde.”

They were the Country Music Association’s duo of the year in 1970 and 1971, recording hit duets including “The Last Thing on My Mind.”

Parton’s solo country records, such as her autobiographical “Coat of Many Colors,” also began climbing the charts in the early 1970s. She wrote the pop standard “I Will Always Love You” in 1973 after Wagoner suggested she shift from story songs to focus on love songs.

The two quit singing duets in 1974 and she went on to wide stardom with pop hits and movies such as “9 to 5.”

In 2002, Wagoner was elected to the Country Music Hall of Fame.
