The Hobbit - Chapter 05 - Riddles in the Dark

[Tuor in Gondolin]

I (once upon a time) had Jared Lobdell's (edited) Tolkien Compass (now sadly lent and lost), in which the old and new versions are presented side by side.

You might want to check out The Annotated Hobbit, which
gives the versions and discusses them, although my
impression is that the editor of The Annotated Hobbit
prefers the original version and doesn't see a compelling
reason to have changed it..
