Though she was once dubbed "the First lady of Country Music," Tammy Wynette was always much more than Geroge Jones' wife -- her weepy and beautiful singing voice has been gracing country radio stations since 1966. Like Jeanie C. Riley, Wynette rose to popularity with divorcee-themed Honky-Tonk songs, and she and Jones recorded a handful of chart-topping duets before their rocky marriage ended in 1975. Her recordings didn't chart as high in the 1980s and '90s, but she continued to sell out venues thanks to a loyal following. She died in 1998.
