I'm looking for the correct words to the complete last verse of the
song "Old Wabash," the fight song of Wabash College, in
Crawfordsville, Indiana.

The first part of the song is here:

but there is another verse that I can't find online that begins like this:

"And loud and long shall echo the song till hill and valley are ringing..."

and ends like this:

"...whatever befall, revered by all, may she unequaled stand."

lefty I followed the link you provided and I discovered to the right
of the lyrics there was a link to hear old wabash and if you listen to
it the missing verse is included.

Holy cow!  Thanks for the discovery!
