On a more or less related subject, I recently archived a 2005 Radio 3 programme where Stephen Johnson discusses some of the imaginative ways in which Percy Grainger and Ralph Vaughan Williams used folk song material in their compositions. He's joined by Martin Carthy, who sings extracts from "Dives and Lazarus", "Come All You Worthy Christian Men", "Maria Marten / The Murder In The Red Barn", "Come All You Worthy Christian Men" (again) and "Star Of The County Down".

The original programme included a complete performance of Five Variants on Dives and Lazarus by Vaughan Williams which has been edited out of this recording but can be found (in much lower audio quality) by clicking here
