TSDS,The Call,Awakening I really look always forward for the Celtic Woman new specials but always am a fan forward to the new created opening number's.
Because it takes a while for new specials, and new tours:
here are some songs that have since transitioned from time to time
making them well enough as collaborators as fun opener's.
Nil Sen La (SFTH Tour opening version)
Teir Abhaile Ru (Opener 2015 promo, Emerald promos fast version though feels more like a celebratory hit number)
Mo Ghile Mear (if you wanted to)
The other's 2 are Christmas, and Walking in The Air is also, but I prefer to like it to being a solo.
I love to listen and sing my opening songs, but now I want to know the next one to add to my list.x
