Lie helped songwriter pen his biggest hit

Percy Sledge's biggest hit was inspired by a big lie.

Sledge said he penned "When a Man Loves a Woman" after someone told him that his girlfriend had decided to leave him for another man.

Years later, after Sledge earned $36,000 for the song, which first topped the charts in 1966, he bought a car and followed the woman to New York to find out the truth. It turned out she had really moved north for a better job, not another man.

Sledge's sellout concert Saturday night marked the end of the weeklong W.C. Handy Music Festival in Alabama.
