These songs from The Hobbit were sung by goblins chasing Thorin and company to the trees, after their escape from Goblin-town (“Out of the Frying Pan, Into the Fire” chapter).

Fifteen birds in five fir-trees, 
their feathers were fanned in a fiery breeze! 
But, funny little birds, they had no wings! 
O what shall we do with the funny little things? 
Roast 'em alive, or stew them in a pot; 
fry them, boil them and eat them hot? 

Burn, burn tree and fern! 
Shrivel and scorch! A fizzling torch 
To light the night for our delight, 
Ya hey! 

Bake and toast ’em, fry and roast ’em! 
till beards blaze, and eyes glaze; 
till hair smells and skins crack, 
fat melts, and bones black 
in cinders lie 
beneath the sky! 

So dwarves shall die, 
and light the night for our delight, 
Ya hey! 
Ya-harri-hey! 
Ya hoy!
