Ents' marching to Isengard song  (taken from "Treebeard")

To Isengard! Though Isengard be ringed and barred with doors of stone;
Though Isengard be strong and hard, as cold as stone and bare as bone,
We go, we go, we go to war, to hew the stone and break the door;
For bole and bough are burning now, the furnace roars - we go to war!
To land of gloom with tramp of doom, with roll of drum,
we come, we come;
To Isengard with doom we come!
With doom we come! With doom we come!
