When Seamus Ennis used to sing "Rocking The Cradle", he would always make two points -

1 that it was the song from which "Git Along, Little Dogies" derived its tune; and

2 that it was a very ancient song, believed by some to have been originally narrated by Joseph, left "weeping and weary with rocking the cradle, rocking a baby that's none of my own".
