Hank Ballard is chiefly remembered for recording a trilogy of risque R&B numbers: "Work With Me, Annie," "Annie Had a Baby" and "Annie's Aunt Fannie." Yet Ballard's contribution to rock and roll goes much deeper than that. With the grinding guitars, distorted sound and fervid call-and-response of those and many other recordings made for the King and Federal labels, Ballard helped define the sound of rock and roll. He also ushered forth one of its greatest dance crazes, having written and first recorded "The Twist." By the early 1960s, he'd charted 22 singles on the R&B charts, including "Work With Me, Annie," which was the biggest R&B hit of 1954. It sold more than a million copies and spawned more than 20 answer records (including Etta James' "Roll with Me Henry").
