Yeah, I believe the original version of that compilation album was released in 2002.
https://www.discogs.com/master/921767-Various-The-Best-Of-Celtic-WomanI have a copy which I dug up. It doesn't have a date on it, but it was definitely before Celtic Woman.
Aside from the album name and the presence of some Celtic Woman performers causing confusion, the cover users the same image of a woman with the orange hair that Celtic Woman uses.
Anyways, the album has a few good track from non-CW performers. My favourites are:
- Garden of Graves (Rua)
- Lover's Heart (D'Goya)
- Hand In Your Hand (Aine Furey)
Danny Boy and Caledonia (Aoife) are nice too.
