Willie Mae "Big Mama" Thornton (1926-84) performs this blues classic with a very young Buddy Guy in 1965. She first recorded it in 1952 and made it a big hit nationally in 1953. Four years later, Elvis Presley performed his rock-'n'-roll version* on the Milton Berle Show before forty million people and became a national sensation (and the subject of some controversy). His recording sold four million records in the U.S., making it Elvis' most popular single release.
