Hey Record Boy -
I found myself on Napster the other day doing some research on John Hiatt when I came across a 'never released but should've been'. It's a cover of "I Want To Be Sedated" by Hiatt and one of the funkiest bands he's ever played with. It seems clear that the cut was recorded at a concert and the quality isn't great, but it's good enough to blow your socks off! Try it, you'll like it.
