I went to school with a girl that married a former roadie of Johnny Winter. They were friends, so she got to see him, when he came to town.
She adored him, although she didn't have the same affection for Edgar. She liked Johnny's down-to-earth attitude and once commented on his long fingers, which she described as "kinda freaked her out".
Anyway, Johnny passed away. He hasn't been in good health for years and one of the newer videos I saw of him revealed time, and his former lifestyle, had taken almost all he had left.
The man was one of the best guitarists, if not the best blues guitarists.
