In 1940, bluesman Bukka White recorded "Parchman Farm Blues," a lament about being imprisoned in the infamous Mississippi State Penitentiary (2:30). Insightful lyrics, impassioned vocals, great slide guitar, and some nice accompaniment from Washboard Sam to boot! Even though he denied it, jazzman Mose Allison adapted White's song in 1958, titling it "Parchman Farm" and giving the song a controversial punchline (43:43). His version was an unlikely dance hit amongst the British Mods, with an insistent piano riff, solid rhythm section backing, and lots of hipster irony. In 1966, The Blues Breakers took the song on, with John Mayall's harmonica in place of the piano, another great rhythm section (including future Fleetwood Mac-er John McVie on bass), and Eric Clapton in the back, reading his Beano comic book. Finally, back to the States to hear The Traits,  with Johnny Winter, who shreds on guitar and vocals mere months before he finds fame at Woodstock (1:38:59).  Drink some wine, sit on Number 9, and open your textbooks ...
