It is a tribute to Jim MacCann who died on March 5, 2015. He was a great Irish Singer and I encourage you to seek, to listen and to read about this artist.
It could be also a tribute to Grace Gifford, who got married with Joseph Plunkett, a boy that was killed few hours after the weedding, for having taken part in the Easter Risen in 1916.
It could be a tribute to the authors of the song too, Sean and Frank O'Meara.
I wish peace and democracy to be the key of the conflict's resolution, and I wish all you the best!
