There are various sets of lyrics, I prefer the ones below, though probably just chorus, verse chorus and not the whole lot.
Highland Cathedral
Words by Ben Kelly
Land of our fathers, we will always be
Faithful and loyal to our own country.
In times of danger, we will set you free,
Lead you to glory and to victory.
Hail, Caledonia, to our ancient prayer.
In this Highland Cathedral, let our standards bear.
Joining, together, with one dream to share.
God bless the people of this land so fair.
Chorus
Gone is the past, let us start anew.
Let this hope of peace, always remain.
Spirit of Scotia, be strong and true.
Then your children will smile again, again, again, again.
Rise, Caledonia, let your voices ring
In this Highland Cathedral of our God and King.
Whom joy and liberty to all will bring.
Come; let your heart with love and courage sing.
Chorus
Lonely the exile, o'er distant seas,
The home of their birth, gone from their eyes.
Bring back their souls o'er the ocean breeze
To the land where their fathers lie.
Repeat last verse
