This was in an email I received this morning. As usual, it sent me off to freely wander my mind. Chock full of questions and whatnots, I believe this song suits us and what we do for each other here in PC.
There are various, and sometimes conflicting, sources for it.
I believe many people connect it to the military...it's not the only connection and is not the major one.

We carry each other here; sometimes we do the carrying.
**Please note that "brother" is meant for male and female**

Thank you for the many times you have carried me.
Thank you for allowing me to carry you.

My Sisters, My Brothers



The road is long
With many a winding turn
That leads us to who knows where,
Who knows when
But I'm strong,
Strong enough to carry him.
He ain't heavy, he's my brother.

So on we go.
His welfare is my concern.
No burden is he to bear,
We'll get there.
For I know
He would not encumber me
He ain't heavy, he's my brother.

If I'm laden at all,
I'm laden with sadness
That everyone's heart
Isn't filled with the gladness
Of love for one another.

It's a long, long road
From which there is no return.
While we're on the way to there,
Why not share?
And the load
Doesn't weigh me down at all.
He ain't heavy, he's my brother.

He's my brother.
He ain't heavy, he's my brother...
