On November 22, 1981, in the middle of a huge American tour, the Rolling Stones arrived in Chicago for a three-night run at the Rosemont Horizon. On their night off, several of the Stones hit Buddy Guy's club, the Checkerboard Lounge, to see Muddy Waters and his band (which featured guitarist John Primer and harpist George "Mojo" Buford at the time). An impromptu blues jam ensued, and before the night was done, Mick Jagger, Keith Richards, Ron Wood, Ian Stewart, Lefty Dizz, Junior Wells, and Guy himself had all appeared on the stage with Waters and his band. This very special night was both recorded and filmed, and portions of the set began appearing as bootleg and unofficial releases almost immediately, and have continued to appear in various configurations ever since across all formats.
