The Ducks of Magheralin is an Irish Polka, with its namesake representing the 'ducks of Magheralin', who were the weavers of the town because they used duck grease to lubricate their looms.^[6] In the preface to a well-known version by the Glenfolk Four, the singers insist that the intent of the song is to address the "myth" that the capital of Ireland is Dublin. The first verse is as follows:

It is just about a year ago that I went to see the King/Queen,

And on my voyage in Ulster my troubles they were twin;

He/She decorated me with medals, and they were made of tin,

"Go home," says he/she, "you skitter ye. You're the Mayor of Magheralin."^[7]
