As the treed Gandalf, Bilbo, and the Dwarves are getting closer to burning, the goblins continue to sing:

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!
