The estate of Roy Orbison is being sued by the Nashville publishing company Acuff-Rose Music Inc. over some of Orbison's recent songs. A federal suit says Orbison's widow, Barbara, persuaded her husband to breach a five-year contract he signed in 1985 to write 10 songs a year in return for $70,000 annually. Acuff-Rose says that Orbison never delivered the songs despite being paid for the first year and that he instead published the songs on his own with many of them showing up on his posthumously released album "Mystery Girl." Acuff-Rose is seeking $1 million in damages, plus triple the profit collected by Orbison's music publishing house, Orbisongs, for tunes written between July 1985 and the singer's death in December.
