I was asked by David T to play this tune. He heard it from a Cd of Harry B who called it "The Old maids of G". I learned it years ago from a book by Brian V under the name "Johnny When You D".
Here's one I heard on a record of Frankie Gavin and Paul Brock. I think it's also on Frankie Gavin's flute LP which is one of the best commercial flute recordings I've encountered. I don't spend all my time encountering commercial flute recordings. If I did I don't know what my opinion would be.
