A Nation Once Again - Irish Rebel song

one of my personal favourite irish rebel songs, the lyrics are very poetic and idealistic. footage is from the irish civil war and the irish war of independence.
Lyrics:
When boyhood's fire was in my blood
I read of ancient freemen,
For Greece and Rome who bravely stood,
Three hundred men and three men;
And then I prayed I yet might see
Our fetters rent in twain,
And Ireland, long a province, be.
A Nation once again!
A Nation once again,
A Nation once again,
And lreland, long a province, be
A Nation once again!
And from that time, through wildest woe,
That hope has shone a far light,
Nor could love's brightest summer glow
Outshine that solemn starlight;
It seemed to watch above my head
In forum, field and fane,
Its angel voice sang round my bed,
A Nation once again!
So, as I grew from boy to man,
I bent me to that bidding
My spirit of each selfish plan
And cruel passion ridding;
For, thus I hoped some day to aid,
Oh, can such hope be vain ?
When my dear country shall be made
A Nation once again!
Non-included line:
It whisper'd too, that freedom's ark
And service high and holy,
Would be profaned by feelings dark
And passions vain or lowly;
For, Freedom comes from God's right hand,
And needs a Godly train;
And righteous men must make our land
A Nation once again!
