So my sister has asked me to do a reading of a poem of my choice at her wedding in a few weeks and I'm planning on doing 'The Road Goes Ever On' because I think it's both a lovely poem and really pertinent to the circumstances behind the wedding, which I won't go in to. However, a few people have mentioned how the line about the 'horrors in the halls of stone' doesn't make a lot of sense outside the context of the Hobbit and I've been told that I should try to find a way to replace that line with something more in keeping with the tone of the rest of that last stanza. and that doesn't come out of nowhere at a wedding ceremony.

Not being a particularly able poet, especially not one of Tolkien's level, I was wondering if anyone here would help?

for anyone that needs a reminder, the stanza in question goes:
'Roads go ever ever on
Under cloud and under star,
Yet feet that wandering have gone
Turn at last to home afar.
Eyes that fire and sword have seen
And horror in the halls of stone
Look at last on meadows green
And trees and hills they long have known.'
