Bonnie Lou started recording rock and roll in a style later called rockabilly. In 1954, she recorded the song "Two-Step Side-Step", written by Murry Wilson, father of the Beach Boys Brian, Dennis, and Carl Wilson. In 1955, she released her first rock and roll record called "Daddy-O". The song rose to 14 on the "Billboard" chart and turned Bonnie Lou into a rock and roll star overnight. It wasn't until 1958 though that Bonnie Lou had another hit, a duet with Rusty York called "La Dee Dah". They soon recorded a Teen Pop song together called "I Let the School Bell Ding-a-Ling".
