Obviously Ford "Snooks" Eaglin is not a famous name ever among blues collectors resp. mudcatters because he is not mentioned so far.
He's a lot more than a country singer. Just listen to his version of "Alberta" or "I'm a country boy". This is Leadbelly-like without Huddies great technique but a swinging guitar-playing. Or listen to "The walking blues" which remembers me of great L. Hopkins. He's a very versatile musician. Right?
