Jo Ann Campbell was an American pop singer known for her versatile style, which ranged from rock and roll and rhythm and blues to country and novelty songs. Rising to prominence in the late 1950s and early 1960s, Campbell released several significant singles such as "I'm the Girl from Wolverton Mountain" and "Bobby, Bobby, Bobby". Notably, she was one of the few female singers of her era to write some of her own material. Despite her relative obscurity in later years, Campbell's eclectic musical style and contributions to the rockabilly genre have acknowledged her as a significant figure in music history.
