I used to sing this song at church quite often, I have the lyrics as:

I climbed a mountain, TO SEE the other side
And I can REST now FOR I AM satisfied
I saw a rich LAND WHERE EACH MAN HAD HIS SHARE
I saw a free land with freedom everywhere.

And there WAS peace in the valley
THERE WAS hope in the land
THERE WAS joy in the children
THERE WAS love, beautiful love in the heart of man.

I saw a schoolhouse where every child could come
I saw a table that welcomed everyone
I saw a city that had no slums to hide
I saw a prison that had no one inside.

And there was peace in the valley...

I saw a lion lay down beside a lamb
I saw a white dove asleep upon the sand
And I saw Caesar give up his mighty throne
And I saw Johnny WHEN he came marching home.

And there was peace in the valley....
