Murray, for your own welfare, avoid the Unicorn. It takes a life of its own and we have somehow cultivated a pro- and con-Unicorn faction when we play at our local pub. People will send money for us to both play and ignore; whoever sends the most wins. We also made the mistake of using Unicorn lyrics in Psycho Killer once (again a compromise) and that has also gotten out of hand.

In addition to the above, I would suggest "A Nation Once Again" and "God Save Ireland"
