This is the lyrics from the movie version for those who were wanting them. I'm listening to it right now, so I have the right ones:

I was standing by my window,
On a cold and cloudy day.
When I saw that hearse come rolling,
for to carry my mother away.

Will the circle be unbroken,
By and by, Lord, by and by?
There's a better home a-waitin'
in the sky, Lord, in the sky.

Lord, I told that undertaker,
"Undertaker, please drive slow.
For this body you are hauling,
Lord I'd hate to see her roll."

Will the circle be unbroken,
By and by, Lord, by and by?
There's a better home a-waitin'
In the sky, Lord, in the sky.

I will follow close behind her,
Try to hold up and be brave.
But I could not Hide my sorrow,
When they laid her in the grave.

Will the circle be unbroken,
By and by, Lord, by and by?
There's a better home a-waitin
in the sky, Lord, in the sky.
