I've also had a song prepared for when Frodo crosses the Ford with the Ringwraiths chasing him down. It should be sung to the tune of "When the Levee Breaks" by Led Zepplin:
When The Bruinen Floods
If you keep on harassing Frodo, Bruinen’s goin' to flood,
If you keep on harassing Frodo, Bruinen’s goin' to flood,
When The Bruinen floods You'll have no horse to ride.
Mean old Elrond gonna make the Bruinen flow,
Mean old Elrond gonna make the Bruinen flow,
He's got what it takes to make a river come crashing down,
Oh, well, oh, well, oh, well.
Don't it make you feel bad
Frodo’s stronger than you thought?
He stood against you and won’t give in!
If you're goin' down South
Sauron’s got work for you,
Way down in Mordor.
Wailin' won't help you, screechin' won't do you no good,
Now, Wailin' won't help you, screechin' won't do you no good,
When the Bruinen floods, Nazgûl, you got to move.
All last night tumbled in the flood waters and moaned,
All last night tumbled in the flood waters and moaned,
Thinkin' about how close you were in bringing The One Ring home.
Going, going to Mordor... Going to Mordor... Sorry but you have to make it ...
On your own... on your own... on your own now....
