you guys need to watch the movie "cadillac records", which is really about chess records in chicago. it is aired on pbs channels occasionally. gives a history, sort of, of early black rock and roll pioneers. muddy waters. willie dixon, chuck berry, etta james and leonard chess to name a few. great watch. at the end of the movie there is a update on each of their lives. if i remember correctly chuck berry successfully sued the beach boys for $1 million for stealing one of his records and changing the words (surfing usa). also, again if memory serves me (it's been several years since i saw the movie) chuck berry went to prison (served 20 months) at the height of his career for transporting underage girls across state lines for immoral purposes. willie dixon also successfully sues led zeppelin. highly recommend the movie for anyone interested in rock and roll history.
