Yes, I forgot to mention that my grandma and mom sang it as I was being bounced on their knees and when the Whoa! came they'd drop me down between their legs- lots of hilarity.

Fun to find the origins of the song, but even better to have it go "into the tradition"... They sang a bunch of these types of songs- probably snippets from music hall or pop stuff from early 20th century. So does it now qualify as folk music since I learned it from them with no idea of origin?
