Like you said in your "Best Song Version Part 1" post, this shouldn't be a happy song. It should have a more serious tone to it.  I can see Muirgen singing it, in the tone of "A Stór Mo Chroí" on the 20th. So I voted for her.
I wholeheartedly agree! 
I hope that a rendition by Muirgen would sound like the Clannad version (here: 
https://youtu.be/OxfxbdPNQvQ?si=s_es7YDfeMbwT_If) with the sombre tone and inclusion of all the verses. I do hope they might include all of the verses someday! The original left out the last two and the 
Destiny and 
Ancient Land versions left out the third and fifth verses. (Although I can kind of understand using only three verses for the 
Destiny version with one verse for each vocalist.) 
It would also be wonderful to have Tara on the harp again! (assuming she’s back, of course 😬) The song sounds a bit incomplete without a harp in my opinion.
