One item in The Roving Songster that might be of interest is the version of "Queen Among the Heather" as sung by Belle Stewart. It's a bit different from the version in MacColl and Seeger's Till Doomsday in the Afternoon. Since Brune knew Stewart before they did, I'd guess it reflects the way she sang it when younger and less in the public eye? I don't see that later one in the Digitrad, is it there? If not I could post both side by side.
