This early '70s yearbook photo is from one of country music's all-time greatest female vocalists. One could make a strong argument that her music and career is as important as those of legends like Dolly Parton, Loretta Lynn and Patsy Cline. This singer is still very active today and still making new fans in members of the younger generation.

However, she never leaves her true fans freezing for new music for very long.
