"Young Andrew" (Roud 6740, Child 48) is a traditional folk song.
[1] Andrew seduces Helen and tells her he will fulfill his promise to marry her only if she brings him her father's gold.
Her heart breaks, killing her, and her father regrets it.
Meanwhile, Andrew encountered a wolf in the woods, and it killed him; the gold still lies by his body.
[2] This tale is found in German, Polish, and Danish variants.
