ArthurI have words to the Kingstown one - will try to type up part at least when I get a chance. Don't seem to have "Castlehyde" anywhere - though I know of a few books which have it. One of Healy's "Songs from the Pubs of Ireland" books may have it - anyone got a copy? I'd expect broadside copies to exist, but a quick search in the Bodleian draws a blank.
The term "hedge school" would be applied to anything before the advent of the National Schools - early 19C., incidentally.
