The Decatur Book Festival kicks off this weekend. We bring you a preview of the authors and artists who will speak at this year's event. Frank Hamilton is a legend in the American folk revival scene. He performed throughout the 1950s and 1960s with The Weavers and Pete Seeger. Hamilton now runs a folk music school in Candler Park. Students gather to learn instruments like guitar, fiddle and banjo, and to jam with Hamilton. We stop by the school for a music lesson, and talk to Frank Hamilton
