Thought I'd resurrect this thread to say it inspired me-- I'll be singing in a vocal competition at a small feis at a celtic festival in July ("small" = "I will probably be the only competitor," especially since it is not well-advertised in the Celtic Festival as a whole), and unless there's a set list of songs to choose from, I will probably be singing this for my Irish Gaelic piece (not sure yet what I'll choose for the English piece). I'd had no idea what I might sing in Irish and thought perhaps I wouldn't enter that section, and then I remembered this.

Since I'm not sure if they'd prefer to hear the Old Irish or Modern Irish version, I may just sing a couple verses of both... now to start practicing!
