Honestly, this is a bit of a problem for me as I could never pick a favorite song that Mairead Nesbitt has done. This is odd since I can figure out a favorite for a lot of the other members. I do know that I don't really like The Last Rose Fantasia as much as it just seems like she's doing scales and it doesn't sound as good to me as other songs.
I enjoyed it but I do love some of her other songs even more (Coast of Galiçia, Granuaile's Dance, any of the Shenandoah combos, There Is No Light / There Is No Night, Hills of Ireland ... she's amazing
