John Fahey also wrote several biographical books about bluesmen. I believe he wrote one about Charlie Patton. They were distributed by an outfit called Legacy Books. I handled a few of them in 1978 when I worked for a publisher in Baton Rouge.(Legacy Publishing-coincidentally no relation) I imagine they're somewhat rare. If anyone knows where to find any copies of these books, or has knowledge of them, I'd be interested to hear from you. Thanks. Kevin
