Origins of "If I didn't have bad luck...
 

...I wouldn't have any luck at all!"

or

"If we didn't have bad luck we wouldn't have any luck at all!"

I done several internet searches and come up blank?

Does anyone know where this came from?

I just remember the Albert King song and then Cream using it in their later song. I don't know if it was around before that.

from wikipedia: "....Born Under a Bad Sign is a blues album by Albert King, recorded between 1966 and 1967, and released in 1967 by Stax Records. This was the first album Albert King recorded on Stax, and the title song became a blues standard.

Eric Clapton copied from note to note the solo of "Crosscut Saw" for Cream's song "Strange Brew" and the band covered the title song for their 1968 album Wheels of Fire..."

As a Brewmaniac I would have thought you knew Strange Brew ;)

It's just a blues line. My second favorite one as it happens.

My favorite is "I'm down so low if I cheered up I'd still be depressed"

Very familiar with Strange Brew both as a song and something I've drank and I knew cream used the line but didn't remember Albert King using it but I just assumed it had deeper roots. Thanks dude!
