Many of the great blues musicians perform(ed) into their senior years. They just got better or do ya'll consider them washed up has-beens. I'd have given my eye teeth to have seen Muddy Waters, Lightnin' Hopkins, Sonny Boy Williamson, Howlin Wolf and many others at any point in their careers. The Stones have'nt been successful all by them selves. Werent they inspired by some of the blues musicians I just named?
