I have tried to render the above song into a more idiomatic (and hopefully more poetic) English (though I'm afraid it's still not singable):

DELIVERANCE

The time of deliverance is coming.
Far from us any idea of revenge.
We will keep our friendship with the people of France,
But we will tear down the shameful walls
That block our view to the sea,
The watchtowers that barricade us from our nearer brothers
In Wales, in Scotland, and in Ireland;
And we, whose name, known to gulls and cormorants,
Was banished from all human languages,
From all libraries, from all terrestrial charts--
We will open our hearts,
The hearts of peasants and sailor-fishermen, to all the people
Of the planet Earth;
And we will offer our eyes to the world.
Is it pretentious to believe ourselves equal?
Is it too much to ask, to want to live?
We will make the rain fall on the wounded world
And wash away the greasy blood that nourishes
The so-called powerful ones,
And give a drink to those thirsty for justice;
And the leaves will grow again in Brittany and Spain
In Mali and Chile, in Indochina and Palestine.
Brittany, center of the inhabited world, you will be a
Refuge for exiled petrol-soaked birds,
For women tortured in prison,
For bombarded old men.
Celtia, at the crossroads of the people of North
And the South, at the juncture of the Old World and
The New World, at the border of the land
And the sea, at the limit of the visible world
And the invisible world...
