The notes to Ballroom properly attribute the origin of the song.

Dolores learnt this song some years ago in Newfoundland, where it's so popular it's almost a second national anthem. In fact, it is an American song, collected in the late nineteenth century in Ohio, but it has only survived in oral tradition in Newfoundland.

To be more specific, it was copyrighted in Cincinnati in 1877, with words and music by Bobby Newcomb. Whether it was a reworking or an original by Newcomb, I don't know.

Good album, Tiger, you can't go wrong with it.
