Maybe. But tunes like "Quittin' Time" were core to the country audience back then. When I was running WTNT in Tallahassee in a very traditional leaning market that was one of our biggest hits at the time.
Everybody has someone who opened the door. In Chapin's case, her music fit with Kathy Mattea and Suzy Bogguss. All three point to Emmylou Harris as an influence. Emmylou points to Loretta. So there's always a country connection.
