From 1961, please enjoy the wonderfully mush-mouthed, laid-back and squeaky stylings of Jimmy Reed and his immortal ode to a downhome girlfriend going uptown for a walk on the wild side, "Bright Lights, Big City."
And then from 1963 and their quite amazing IBC demo sessions (pre-the first album, produced and engineered by the great Glyn Johns), ponder The Rolling Stones apotheosis of the Chicago Blues-style cover version.
And, finally, from 1965, here's The Animals, featuring the tremendous organ phrases of Alan Price, and their sort-of jazzy revamp of the tune.
I love all three of these, but I've mostly had a soft spot for the Stones version, which I heard for the first time on the bootleg pictured above in 1973; I was stunned then, and still am, that a bunch of pimply Brit kids had that Chess Records vibe down so absolutely cold.
That said, on revisiting the Animals take, I'm unexpectedly impressed. It verges on, dare I say it, pop, doesn't it? And those rhythmic shifts are really clever...
