[Girl in the Grass]

I don't think the dwarves' song will make it in, or any of the songs for that matter. As for Riddles in the Dark, I have a feeling it will be cut out entirely, with Bilbo just finding the ring, maybe a short confrontation with Gollum, and then getting out of the caves. Beorn's helper animals are probably going to be cut as well. I have a sneaky feeling the dungeons of Mirkwood are going to go the way of Tom Bombadil...
