On Highway 57, somewhere between Frog Level and Smyrna, stands a gas station. Across the blacktop is a roadside eatery called the Double Cupp Diner. The four guys at the station, Jim, Jackson, Eddie, and L.M. have been known to do some auto repairs, but only when aided by quantities of time and beer. The Cupp Sisters, Prudie and Rhetta, celebrate their home cooking with the same zeal they bring to being neighborly with the boys. Together, performing on guitars, piano, bass and, yes, kitchen utensils, they fashion an evening of country western songs that received raves on and off- Broadway.
