All I could find with any similarity to your request was the song I Is A Newfie by the Arrogant Worms. It's chock full of words like dat's, dis, dem, de, and a even a dat dere, but I don't see an Irish connection since the Arrogant Worms are from Canada. You can try the search engine at GEST Songs of Newfoundland and Labrador if you like. :)
