Hi there!
I have been in a serious search after a song which I used to listening to when I was 12 years old (I’m now 19, so it was about 7 years ago. The song was on a tape and the the tape contained a lot of Michael Flatley songs too, so I assume I am talking about one of the “Celtic Tiger” songs. Unfortunately this tape has gone, I can’t find it anymore, and I neither remember the name of the band and the name of the songs, but 90% sure it was one of the Michael Flatley songs. I only remember a woman singing. There were about 5-6 strophes and two types of refrains, which interchanged each other, so there was the first strophe, after it the first type refrain, then the secound strophe with the secound type refrain, then the 3rd strophe with the first type refrain. And I think the refrain was sung by more than one woman. Oh, and about the language: I am not sure, it was not English for 99% sure, it was rather irish or gaelish or some language I don’t speak 
If you can HELP me, I’d really appreciate it! Thank you forward!
