Paddymac, sorry I don't have the names of the two different airs. A Mayo woman sang the "minority" air here live a few weeks ago (Glasgow) and called it the "Mayo" tune, Joe Heany, from Connemara, also used it, so possibly from the west of Ireland. Yea Sinead O'Connor is a fine singer of trad songs, the girl (to me) has soul. She has also added Margaret Barry's version of Factory Girl to her stage act.
