We know that limericks have been sung and not just recited for a long time. Stan Hugill even gives a "Limerick Shanty" that he learned at sea, and Charles J. Finger refers to the singing of limericks in his own experience as far back as the 1890s.

It's been said that the name "limerick" comes from a "lost" chorus made up of or including the phrase "Won't you come up [or down] to Limerick?"

Has anyone ever heard such a chorus? When and where? How many different choruses are in use today?

As most 'Catters know, bawdy limericks are sung at endless length, especially in British, Irish, and rugby circles. But are clean limericks ever sung, or are they always simply recited one or two at a time? Is it mainly university types who memorize limericks at all?
