You can find plenty of write-ups about Chuck Berry and his death at age 90, such as here and here. However, one lesser known fact about Berry was mentioned in this article:
There was a also a darkness and suspicion in Berry, for those who cared to look. He was notorious for making concert promoters pay him in full before his shows, cash only.....Years later he was convicted of tax evasion.
I learned about his concert scam a long time ago when he was brought in to perform at the Elkhart County Fair. One of our friends was on the fair board, and the board had caught wind of Berry's tactic. So, shortly before going on stage, Berry demanded more money or else, no show. The board had a check made out for the sum requested - Berry went on to perform, but the board had the check cancelled immediately. I never did hear of any consequences, so Berry must have chalked it up to being scammed on his scam.
