I like the songs sung by the Celtic Women. Some more than others. I just was listening to this song and it struck me that there might well be many meanings. A sailor leaving for a voyage, someone near death.
Also, if you watch the enthusiasm of the band as the lady begins to play the fiddle, they are smiling they are into the performance. They enjoy the song, not just playing the instruments.
Anyway, just thought I'd share.
