Ivory Joe Hunter (October 10, 1914 – November 8, 1974) was an American rhythm and blues singer, songwriter, and pianist. After a series of hits on the US R&B chart starting in the mid-1940s, he became more widely known for his hit recording, "Since I Met You Baby" (1956). He was billed as The Baron of the Boogie, and also known as The Happiest Man Alive. His musical output ranged from R&B to blues, boogie-woogie, and country, and Hunter made a name in all of those genres. Uniquely, he was honored at the Monterey Jazz Festival and the Grand Ole Opry.
