Mick, I used to have Molly Bawn, with the words as above, on a Ryan's Fancy LP. I don't think I have it any more. Unfortunately nothing by them is out on CD, except for one unauthorized CD with bad sound.I can't remember any more of the lyrics except snippets "She was young and beautiful" (what loves in folk songs are anything but?:)) and something about "The days I spent with Molly Bawn/A-boating on Lochree(sp)"
The song about the lady shot as a swan I do have, and could probably dig it out. There are variants of this in the data base under Molly Bawn and Polly Vaughn. I'll see if I can locate the tape I have this on.
