In 2003, Chicago blues guitar legend Hubert Sumlin recorded an album called 'About Them Shoes', which features him playing covers of two other great bluesmen; seven Muddy Waters tracks and five Willie Dixon tracks, with one written by himself. The album also features Eric Clapton and Keith Richards (of The Rolling Stones). A stellar traditional blues album on all accounts.
One of the covers, 'Iodine in My Coffee', is very true to the original 1952 recording, which Muddy Waters would be proud of.
Here's the cover, and below it the original:
