Known in England as "Polly Vaughn" and in the United States as "The Shooting of his Dear," this come-all-ye reworks an ancient folk theme. In the Hebridean version, it is the cruel mother who advises her son to shoot a swan, even though she knows that the swan is his true love.
I was wondering if there is a version like this? Perhaps it ties into the Irish story "Aislinge Oengusso" or "The vision of Aonghus" also Aengus. Anyone?
