Will The Circle Be Unbroken lyrics

I was standin' by the window on a cold, cold cloudy day
When I saw that hearse come rollin'
For to carry my mother away
Will that 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 said, mister undertaker, undertaker please go slow
'Cause the woman that you're takin'
Oh, well I hate, I hates to see her go
Will that circle be unbroken
In the sky, Lord, in the sky
There's a better home a-waitin'
In the sky, Lord, in the sky
