About Willie Mabon
Willie James Mabon was an American R&B singer, songwriter, pianist, and harmonica player. He had two number one hits on the Billboard R&B chart, "I Don't Know" in 1952 and "I'm Mad" in 1953. He also was the first artist to record Willie Dixon's "The Seventh Son". However, his career failed to maintain its momentum, and record releases in the late 1950s on various labels were largely unsuccessful.
