Wow, none of these are the version I was taught as a child, which I'd love to have someone here remember for me (consider this an Oh, Yeah, and Here's Another Lyrics Request). It ended in a verse that went:

Build a road of peace before us
Build it wide and deep and long
Speed the slow, remind the eager
Help the weak and guide the strong
None shall push aside another
None shall let another fall
Work beside me, O my brother
All for one and one for all!

...but I don't remember the first 2 verses. Anyone know this one?
