The Wehmann version looks as if it has been sanitised. The second verse is completely out of theme with the first. To me the style is very much 1870s/1880s American Music Hall much in the same vein as Chickens in the Garden though that one is more sentimental. The many quite different versions would give us a date going back at least to the 1880s. Very popular pieces like this were soon parodied and rewritten. It shouldn't be too difficult turning up the original if that is the case.
