For anyone interested, I just stumbled upon the Arhoolie Foundation website. Has a few nice interviews with Canray Fontenot, Chuck Guillory, D.L. Menard, and one pertaining to Harry Choates.
Thanks John for digging out this wonderful website. These audio interviews are really great and moving. And what a good idea to have put the transcriptions! It makes it much easier for us non-native English speakers to follow what the musician says. I have only listened to Joe Falcon so far and I enjoyed hearing these stories first-hand. First time I hear his spoken voice too (so soft and pleasant!). I'm going to listen to several others.
Thanks again!
