[Brinniel]

Here's my attempt. Sorry if it sounds dumb. I'm not much of a songwriter.

(To the tune of "Jolly Old Saint Nicholas" sung by Gandalf)

Frodo Baggins; come here lad
Lean your ear this way
Don't you tell a single soul
What I'm gonna say
Nine Ringwraiths are coming soon
They are looking for your ring
You must flee from Hobbiton
And destroy it if you can

Samwise has been eavesdropping
He will come with you
Into Mordor you will go
And destroy the ring
Many troubles will pass you
Orcs and trolls and wraiths
Just make sure you complete the task
And save Middle-earth
