Alright then, here's my selection from Live.
It's called 
I Alone, and it's regarding Bilbo's little run-in with Gollum in the Misty Mountains, the Riddle Game, & what alone can save him... (Luck, of course)
it might be easier not to be wise 
and figure these things by your brains 
You're stuck in the Mountain with him
alone by the lake by and by 
You cannot see much save his eyes 
you're bothered by them he can see
your time is up you get your riddle away
but the greatest of tricksters won't hesitate 
to squeeze you there by yourself clinging to fate
 
I alone can save you 
I alone can help you 
I alone can save you 
will you come to end like this?
it might be easier not to be good
and figure these things tho 'praps you could 
you long to be free of this bargain 
alone by the lake by and by 
to search through these tunnels on your own 
and leave him there by himself all alone
but his appetites come back to far
only LUCK can save you now 
all these riddles that you've learned
won't do any good to you 
you want to go and hide 
only LUCK can save you now 
all these riddles that you've learned...
yeah, yeah, yeah
