Barbara Orbison, 60, widow of rock-and-roll pioneer Roy Orbison, died Tuesday on the 23d anniversary of her husband's death, a family spokeswoman said.

Barbara Orbison died from pancreatic cancer at Los Angeles County-USC Medical Center surrounded by her sons, said publicist and family spokeswoman Sarah McMullen. She had been hospitalized since May.

Since the 1980s, she devoted her time to managing her husband's estate and keeping his legacy alive.

With her son Roy Kelton Orbison Jr., she produced a four-CD box set of her husband's 107 recordings. Roy Orbison: The Soul of Rock and Roll was released in 2008 and contains all of his hits and 12 previously unreleased tracks. The package marked the first all-inclusive body of Roy Orbison's work, from his earliest recordings to the Traveling Wilburys' debut album, Mystery Girl, and his last live performance.

He died in 1988 at age 52, in the midst of a comeback with the Traveling Wilburys. - AP
