Hello, I am searching for the title from a song from the irish folkore band Derwish. The song is the first song in this video:

I have understood the following words in that video: "dabault darty" and in the refrain I heared: "father die do" I searched with google with the words but unfurtunally without any success.

Friendly greeting from Moe Perry
