I remember this song, too, from 4th grade. Not sure what the title is - On My Way or I May Not Pass This Way Again. Something like that. This is what I remember:
I'm on my way to find a friend
And I may not pass this way again
So let's go build the bridges mister
Let's go run the ridges sister
Come along stranger come along friend
I may not pass this way again

I'm on my way to find a friend
And I may not pass this way again
So let's go climb a mountain mister
Drink from a bubblin' fountain sister
Come along stranger come along friend
I may not pass this way again

I'm on my way to find a friend
And I may not pass this way again
So let's go something something mister
Let's go pick the flowers sister
Come along stranger come along friend
I may not pass this way again
