Hi Master, you might find this info at Lesley Nelson's site helpful, especially the historical links she lists. The Foggy Dew [http://www.contemplator.com/folk4/fogydew.html]I see you found the Mudcat discussions on the song and lyrics, but did you see all the hits when you put "foggy dew" (without the quotes) in the search box?
I'm also interested in hearing more. One of our members sings for us on PalTalk and says her father used to sing that one. I would love to hear her sing it because she has a gorgeous voice trained in the Irish folk style of singing. (Noreen!) This song is so hauntingly beautiful!
