I just heard/saw Loreena McKennitt sing this song on You Tube, from Barnes and Noble to introduce her new Ancient Muse. I know I have heard this before. What strikes me about the song is just how 'Irish' it is. Meaning that I feel like I am walking down Grafton Street. It does for me what Irish/Celtic music has always done for me. It makes life liveable, when it didn't seem that it was. There is an inner voice that speaks to me through this kind of music that has carried me through life's struggles when I was out of strength. That is about as well as I can explain what I feel when I hear this.
