Loretta Lynn’s youngest sister, Crystal Gayle turned into a country star in her own right, scoring nearly two dozen number-one country hits throughout the ’70s and ’80s, including her signature 1977 hit “Don’t It Make My Brown Eyes Blue.” The long-haired singer still tours regularly, though she hasn’t released an album of new material since 2003’s All My Tomorrows, which followed a number of Christian-themed albums.
