Thanks, Masato. I was surprised at the "earliest date" of 1877. although the "would not sing" versions smack of 18th/19th century glee clubs and the likes of the Anacreontic Society (whence that peculiar tune to "The Star-spangled Banner"), precursors of the Brotsh Music Hall. I always expect traditional songs to make sense, more or less; but "popular" songs are not infrequently nonsensical.

It sounds like the "would not sing" version may be related to Old King Cole . Cole was a 5th century Welsh (or Scottish) king, predating Arthur by a couple of centuries (my arithmetic was a bit out in my first post!), and much given to musical pursuits, according to his song.
