Louie, that book must be a real treasure. I'll bet my dad had the same one back then. Thanks for posting the lyrics as Curly wrote them.
Joe, I would think the way Curly wrote them, as documented in the earliest printing, would definitely warrant being in the DT. I can't get at my Lomax right now, but as near as I can remember those are the same words and they look the same as what my dad sings.
I love this song, it is part of my very earliest childhood memories. We children were always requesting it of dad.
