She had moderate success in the late 1950s with "Wait A Minute", which she wrote, "Nervous" and the ballad "Happy New Year Baby" which many thought would become a holiday standard. In the 1960s, her biggest hit, Top 40 on both Pop and Country charts (USA), was "I'm The Girl From Wolverton Mountain" (1962), an answer song to Claude King's "Wolverton Mountain." Jo Ann's other successful records in the '60s include "A Kookie Little Paradise,", her biggest hit in the NYC area, reaching the local Top 10 in the summer of 1960, "Mother Please," and "Motorcycle Michael".
