smokestack lightning / you can't be beat
Wolf had performed "Smokestack Lightning" in one form or another at least by the early 1930s when he was performing with Charley Patton.
the chicago blues master said the song was inspired by watching trains in the night: "We used to sit out in the country & see the trains go by, watch the sparks come out of the smokestack. That was smokestack lightning." The song is coupled here with its original 1956 b-side 'you can't be beat'.
