There were no musicians in my family except for my grandmother who played piano in church. My parents were part of the left wing so we had Woody Guthrie 78 rpm records and other left wing union and popular records. In southern California there was all kinds of music on the radio: Country & Western, Dixieland, Jazz; R&B, and gospel.
That is too complicated for me to answer. But there were lots and lots of people involved.
