Fascinating discussion here! I just yesterday discovered Hillery's thesis, and immediately found inspiration to sing one of the Jack Beeforth numbers in there (in my own, self-taught way). It's got me down a wonderful rabbithole for the next while. This line of research is well up my alley. I have a great passion for the preservation and unearthing of authentic and often obscure folk arts, particularly in giving new life to old, forgotten/underappreciated poetry. In this way, I personally love to recite or sing a song however speaks to me, not knowing how it is 'supposed' to sound (John Dowland's lyrics have been a great interest to me this year). Anyway, it would be a pleasure to hear the music that is attached to the thesis, but doesn't seem to have made it online (as of yet at least!).
