...might be FOTR when the hobbits would see the Elves on their way to the West.

I believe that's correct and it has been added to the extended version.

Yes, that is correct, it is a formerly cut scene from the early part of the story, where elves could be seen passing through the Shire on their way west, never to return.

I will not be able to post much today either... busy today, and tonight will be reading up on my chapter for tomorrow!
