The Dukes of Hazzard is just one of many revelations.
With Muscle Shoals, Camalier has gathered a host of celebrities to wax lyrical about Hall and his merry band of musical adepts. Franklin, Pickett, Sledge, Mick Jagger, Keith Richards and Stevie Winwood all sing the praises of the sound of the 'room' and the talented artists they played with time and time again. As you'd expect, there are a fair few stories of flaring tempers, but this is the workshop of music and the players themselves confessed they preferred going home to their families and only toured late in their careers. U2 frontman Bono is also on board to offer his usual eminently quotable guff: "Maybe the music came from the mud."
Hall himself emerges as fascinating character. Someone whose early life was marked by tragedy, he now surveys his history - an eighty-year-old working producer with a lion tamer's moustache - with deserving satisfaction. The second half of Camalier's well-meaning doc pulls away from him as a figure, however, as his success is eclipsed by that of his former protégés. If, as a piece of cinema, Muscle Shoals can at times be a little on the limited side, the music is so good and so varied, the stories so rich and so interesting, you can just close your eyes and listen.
Muscle Shoals is released on DVD from 10 February, courtesy of Dogwoof. For more info, visit dogwoof.com.
