Number 475 in the Roud Folk Song Index. You'd expect a 19th century music hall or broadside derivation for this one, but I don't know of any. At all events, it's been most often found in England, where it seems to have originated, and from where it made its way to Australia, Canada and the USA (one Scottish example appears in Greig-Duncan III). It appears never to have been found in Ireland until the Clancys made a commercial recording of it; presumably they got the song from an English or Australian source.
