I think the song was originally done by another artist, but Declan sings it so well. (Same for tears in heaven, he has a version of that too...)
-- If you can find it, try the original ACM one. I defy anyone to stay dry eyed at the end, when the women and children of the fallen soldiers are revealed.
I'm Already There By Lonestar. I have an audio version that has clips, messages for the troops in the field that's even more tear-wrenching, but no way to share it.
Skin -- You have to listen to the end to really get the impact. The song as a whole is sad; the ending is... beautiful. Beyond words. When she reaches out... and touches just... skin...
I hope you Dance
Have you Forgotten
These are a little less likely to make others cry, but they touched me in various ways:
Depnding on the mood, this one can produce something of laughter or tears... or both. A girl whose own mother is forced, out of desperation, to turn her into a prostitute, because there were simply no other options left. And that girl took it, and ran...
This one isn't likely to get as many of you, but... it spoke to me. Probably my favorite version of this song.
And with that, I think I've posted more than enough... And FYI: my already overclogged sinuses (allergies suck) hate you all!
