Traditional songs: modern singers. Four films featuring some of the pioneers of the folk song revival. 3: Martin Carthy and Frankie Armstrong believe that traditional music is too important and too powerful to be confined simply to the folk clubs. For Martin it is a chain linking past, present and future human experience. For Frankie it is the vehicle that can take her audience on a ' journey'. She proves her point with an electrifying performance of the ghostly ballad ' Tarn Lyn '.
Filmed at the Co-op Folk Club. Nottingham.
