Lord Charles And The Prophets cover Lightnin' Hopkins?

[Lord Aguayo]

I noticed the other day that the flipside to "Don't Ask Me No Questions" by Lord Charles & The Prophets is "Mojo Hand", which I assume is a cover of the iconic Texas bluesman Sam Lightnin' Hopkins. I can't find anything on the net as far as a clip of the song tho. Not that I expected to.

I hardly doubt it's a garage-take, but can anybody maybe provide a sound file or will it stay buried forever? I'd really like to hear that.
