I've wanted to do a version of Old Mother Hubbard for a while, and I finally have. My take is called Old Mr. Moorehouse.
What some people might not know is that Old Mother Hubbard is much longer than the five-line stanza everybody knows. There are about a dozen additional four-line stanzas in which the dog does all kinds of humanlike things. (You can see the original here.) My version doesn't go on quite that long, but enough is enough.
