Here's what Jim says:

Regarding my recitation on July 1, here are scans from the pages of
the book, plus a scan of the first part of the introduction.

You'll see from the intro that the name of the English version is much
condensed from that of the original Danish version, Danske Viser:
Gamle Folkeviser, Skæmt, Efterklang, which I would translate as
Danish Songs: Old Folk Songs, Humor, Refrains. Is that one of the ones you have?

What I consider unusual -- unique? -- about this "song" is the fact
that it involves incest and infanticide, yet the concept of shame is
nowhere mentioned or even implied. Sin... yes (it's mentioned in the
second verse, and the parents are initially sent to hell), but not
shame. Nothing is said about how the parents died... no murder of the
mother or double suicide, which would imply shame. I.e., if there was
shame, it's not considered relevant to the story.

Nor does the child suggest that what its parents have done --
including its own murder -- should bring punishment, judgement... or
even mention. It loves its parents. And although "forgiveness" is
pervasive, through the repeated chorus, it doesn't enter the story
line. The child doesn't call upon God's "mercy", but only on God's love.

Do you know of anything like this in English-language folk song
tradition?
