When I was a youth in Chicago, and dinosaurs roamed in Lincoln Park, one club on Rush Street had Bob Scobey with the great banjo player Clancy Hayes, playing something close to jug band music, and down the street was the Gate of Horn where Bob Gibson played, backed by jazz bassist, Ray Brown, was creating new folk music. Thus, for a brief moment in time, jazz and folk music may have been coming together. But Mr. Zimmerman and Ms. Baez drove them apart. All it would take is someone with the right interest and talent to try again.
