Hey Brian, I can't place the artist either. I know it comes from a blues called 'I'm A Stranger Here'. I thought Sonny and Brownie, but their blues of that title is different. Here's what sticks in my mind - maybe it will prompt someone's memory as to who sang it:

Ain't it hard to stumble when you've got no place to fall?
Ain't it hard to stumble when you've got no place to fall?
In this whole wide world I've got no place at all

I'm a stranger here, I'm a stranger everywhere.
I would go home but, honey, I'm a stranger there

Hitch up my buggy, saddle up my black mare
Hitch up my buggy, saddle up my black mare
Goin' to find me a fair deal in this world somewhere

--Stewie.
