Hello Banjer and thanks for your help, but i have already searched DT about 50 times this year for that song. The singer is (the only version i´ve heard) Dolores Keane on De Dannans First album(I think)

That version contains four verses

I tried to write down the words about 5 years ago, but it was very hard to hear every word clearly(I´m from Sweden) It goes like this:(sorry for bad spelling)

first vers:

"I´m eighteen years old today my ma, and I´m longin to be wed. So buy for me a young man, who will comfort me she said. You must buy for me a young man, who will be with me all night. When I roll him in my arms, He will be my hearts delight"

Anyone who can contribute with more verses?
