As well as the usual dislaimer, please note that this is based, of course, on "Bridge over Troubled Water" by Simon and Garfunkel.

Bridge over Anduin - sung by Faramir, written by Saruman & Glorfindel

When the Nazgûl screech their call
And Haradrim attack, we will fight them all
We will not hide
Oh, when Mordor's might
On all sides us surrounds
Then the bridge over Anduin
We must pull it down
Then the bridge over Anduin
We must pull it down

When it's all in doubt
When we must retreat
When losses fail to guard
I must lead them through
I'll falter not, oh, when shadows come
And darkness us surrounds
Then the bridge over Anduin
We must pull it down
Then the bridge over Anduin
We must pull it down

Ride on Mithrandir
Almost fly
It's not your time to shine
Now is Éowyn's great day
It will be fine
Oh, when she needs a friend
I will be there to find
And the bridge over Anduin
Will again banks bind
And the bridge over Anduin
Will again banks bind
