"Molly Bawn" (Gaelic: "An Cailín Bán") is also known as "Molly Bon", "Polly Vaughn", "Polly Von", "The Shooting of His Dear", "As Jimmie Went A-Hunting", "The Fowler" and other similar variations.
In this relatively recent version, Molly is covered by her white apron and is mistaken for a swan. In older versions, closer to the folk/fairy tale roots, Molly would be a "shape-shifter" who could assume the shape of, or become an actual swan. When she dies, her shape reverts to her actual human form.
It was printed in Edward Bunting's General Collection of the Ancient Music of Ireland (1796).
It has been recorded by Seamus Ennis, A. L. Lloyd, Harry Cox, Peter, Paul and Mary, Peter Bellamy, The Dubliners, The Chieftains with Alison Krauss, John Roberts and Tony Barrand and others.
