American singers never improvise on the Canadian anthem at hockey games. It would be considered disrespectful. But they butcher our anthem all they want.
I prefer the French lyrics to “O, Canada”...
O Canada! Terre de nos aïeux,
Ton front est ceint de fleurons glorieux.
Car ton bras sait porter l’épée,
Il sait porter la croix.
Ton histoire est une épopée,
Des plus brillants exploits.
Et ta valeur, de foi trempée,
Protégera nos foyers et nos droits.
Protégera nos foyers et nos droits.
O, Canada! Land of our forefathers,
Thy brow is girt with glorious flowerlets.
For thy arm knows how to bear the sword,
It knows how to bear the cross.
Thy history is an epic
Of the most glorious exploits.
And thy valor, tempered with faith,
Will protect our hearths and our rights!
Will protect our hearths and our rights!
