HOW COOL! As 14 year old, in 1959, I would ride my Cushman motor scooter From Biloxi Miss to New Orleans to just walk around and listen to the music. Was too young to get in anywhere, but really took in the street music. Never actually saw Fats, but his sound was everywhere, along with the sound of the Neville brothers and lots of others.
It was Fats who "showed" me the importance of a bass line and that it could be played on a keyboard.
Good find, Gary!
