I sat down and made a list of (very favourable) things I thought I should say before posting this song, but then I second-guessed that and thought it might be best to let the song stand on its own merits. For those of you, like me, who might have to look up the words, it's sung in the voice of a mountain in Nova Scotia that's seen generations come and go. The title means "The Blue Mountain's Lullaby." The words are by Jeff MacDonald, and the tune by Brian Ó hEadhra, who sings it here.
Tàladh na Beinne Guirme
And sort of P.S., except that might imply that it's of secondary importance, which it isn't: if you liked that song, just go browse through Brian Ó hEadhra's Soundcloud page, why dontchya? It's grand.
