 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 music, and Hunter made a name in all of those genres.

 However, her success was overshadowed three years later, when Elvis Presley recorded his more popular rendition of "Hound Dog".
