"Jerusalem" by Emerson, Lake and Palmer

And did those feet in ancient time,
Walk upon England's mountains green?
And was the Holy Lamb of God
on England's pleasant pastures seen?

And did the Countenance Divine,
Shine forth upon our clouded hills?
And was builded here
Among these dark Satanic mills?

Bring me my bow of burning gold!
Bring me my arrows of desire!
Bring me my spear: O clouds unfold!
Bring me my Chariot of Fire!

I will not cease from mental fight;
Nor shall my sword sleep in my hand
Til we have built
In England's green and pleasant land.
