Mr. Dylan was nonetheless largely unknown then, however, Mr. Neuwirth stated years later, he caught his eye “as a result of he was the one different man with a harmonica holder round his neck.”

The 2 hit it off, and Mr. Neuwirth grew to become a central determine within the circle that coalesced round Mr. Dylan as his fame grew. When Mr. Dylan held court docket on the Kettle of Fish bar in Greenwich Village within the early Sixties, Mr. Neuwirth was there. When Mr. Dylan toured England in 1965, Mr. Neuwirth went alongside.
