I have discovered that the word I gave as poltóg in the sentence:
"Did you e'er see an Irishman dancing poltóg" should be paltóg, which means
wallop or batter; "battering" being an accepted term in descriptions of Irish
dancing. Also, despite my earlier reservations, Paddy Tunny's Uncle Michael
did sing that word and the entire song in a way very similar to Paddy's.
