I wish I could delete my errors above. You have the right song title; well there is one main street (sráid) in the town of Dungloe (an Clochán Liath) and the song is published in Nollaig O hUrmoltaigh, "Ceolta Uladh 2". a hard book to get, so I'll type out the lyrics and post them here. Where did you hear the song, Nella?
