No, it's not Colcannon. This song was in Gaelic and it sounded as I had said before. Wish I could hum you the tune as I'm sure someone would recognize it. Here's how it sounded to me but the spelling will be phonetic.Brochan long, tannan long Brochan tannan suigan Brochan long, tannan long Brochan tannan suigan
It goes on into a chorus. Hope someone can help. Thanks.
