Many thanks, Anne - it would be great if you could check with him, and an honour to hear from him.

By the way, do you know anything about the origins of the song? The last verse seems to imply it dates to the late 19th century, so the Queen it refers to is presumably Victoria? It can't be 20th century because there were no Queens in that century until the '50s and it can't possibly be that recent. But to me it has the feel of a Scots music hall song, a bit like The Day We Went to Rothesay-o. With such witty lyrics and such a lovely tune it's amazing to me that its authorship is unknown, given that it's not all that old.
