I am 82, and my mother sang a version of this song to me when I was a small child. She had a few other weird nasties as well, all short and sadistic. I think they date from the late 1920's or 30's, along with the sadistic Little Audrey stories. The Ruthless Rhymes featuring the horrid misdeeds of Little Willie (and the calm way his mother accepts them) are even older--can be dated to the 1890's. Our Edwardian and Victorian ancestors were not as prim as we sometimes imagine.
