We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I believe those are tattoos. He and his brother Edgar were albinos so their eyesight was very poor. He battled drug and alcohol abuse for some time and at the height of his career, he checked himself into a mental hospital for treatment (I think that takes an enormous amount of guts on many levels). The drugs may have contributed to his emaciated condition. On the one hand, he was always thin and on the other, he may have been abusing drugs for that long!
It's very sad. I think he was under appreciated (like so many blues players white and black). He was known as on of if not the fastest guitar player.
