Irelands Natonal Anthem is " The Soldier's Song" written by Peadar Kearney or Peadar O cearnaig. It was the rallying song of the patriotic forces during the struggle for Irish freedom which marked the years 1916 - 1921. The air is stirring but is not OLD IRISH MUSIC. The air was composed by Padraig O hAonaig.
The Canadian Anthem is "Oh Canada", I believe that at one time it was "The Maple Leaf Forever" by Alexander Muir but I am not sure about this. I don't know who wrote Oh Canada.
