Jens wrote I think it floats just fine. This is not Eric Clapton and Cream, playing in arecord studio. It's really folk music - hobo music, isn't it? Originally played by people with no education, walking from street to street, playing for the poor people, day-labourers, whores, guests in cheap crummy restaurants etc. That is at least the impression I get from the lyrics in the songs. To me this sound just about right ;-)
The original was done by Robert Johnson and was much closer to that version then Cream's version was. Cream's version is in my opinion is a prime example of English blues rock of the 60's and is in my personal top ten songs of all time. Clapton has since proved he is as adept at playing traditional Chicago blues and is no slouch at acoustic blues either.
