This old folk song shows up a lot in the folk singer community, especially among Irish folk singers. But sometimes pop singers pull up an old folk tune and red-headed comedian Danny Kaye used to sing songs like Molly Malone in his movies and radio appearances. He had that lovely Irish tenor voice that set these songs perfectly.
I especially like poignant sweet melodies like this one. I think it probably inspired The Beatles song, Obla Di, Obla Da which also features a barrow wheeling daughter of fish-mongers. Danny Kaye movies are some of my favorites, but I love listening to him sing too. There's another Danny Kaye melody by his wife Sylvia Fine called Darlin Meggie. I had to go to the Library of Congress to get that video. Enjoy these two beautiful songs.
