To be sung to the tune of "The Ants go Marching One by One".

The Ents go marching one by one, haroom, haroom.

The Ents go marching one by one, haroom, haroom.

The Ents go marching one by one,

With roll of drum, with doom they come,

And they all go marching down into the vale

To break Isengard down.

Boom, boom, boom.

The Ents go marching two by two, haroom, haroom.

The Ents go marching two by two, haroom, haroom,

And they all go marching down into the vale

To break Isengard down.

Boom, boom, boom.

The Ents go marching three by three, haroom, haroom,

The Ents go marching three by three, haroom, haroom,

Not very bendable at the knee,

But they all go marching down into the vale

To break Isengard down.

Boom, boom, boom.

The Ents go marching four by four, haroom, haroom,

The Ents go marching four by four, haroom, haroom,

To break Isengard down.

Boom, boom, boom.

The Ents go marching five by five, haroom, haroom,

The Ents go marching five by five, haroom, haroom,

Not one Orc will be left alive

When they all go marching down into the vale

To break Isengard down.

Boom, boom, boom.

To break Isengard down.

Boom, boom, boom.
