NASHVILLE: The estate of a Mississippi blues musician has filed a lawsuit against Eric Clapton, accusing the Hall of Fame guitarist of giving a songwriting credit to the wrong artist. The Tennessean  reports a lawsuit filed in Nashville federal court says Eric Clapton attributed the song 'Alberta' to Huddie Ledbetter — better known as Lead Belly — in the 2013 re-release of Clapton's 'Unplugged' album, when the credit should have gone to Bo Carter. Miles Floyd, Carter's step-grandson, says Clapton's song was actually a cover of Carter's 'Corrine, Corrina,' which was first licensed in 1929 and over time became interchangeable with 'Alberta.' The lawsuit seeks $5 million and includes Clapton and Warner Music Group Corp as defendants. The defendants haven't responded to the lawsuit.
