Same here...a great loss. I've read up on how he "managed" his performances...GEEZ, he had to go through a lot! He didn't hire any sort of management that would take care of logistics, so every time he got into a new town he had to rent a venue, hire side-players, ad infinitum, just to play his music.
He was a true musician...one who suffered through the difficulties almost all musicians face getting their music out there for the masses.
He must have been good at it...EVERYONE knew who Chuck Berry was and his songs were instantly recognizable.
He'll be showing them how to do it in the afterlife, too!
Cheers to a great, Americian musical icon, Chuck Berry's music will live on, even if he's not.
