Dylan’s music captured the spirit of the tumultuous 1960s, as reflected in the lyrics of “Chimes of Freedom” from 1964: Tolling for the aching ones whose wounds cannot be nursed For the countless confused, accused, misused, strung-out ones an’ worse An’ for every hung-up person in the whole wide universe An’ we gazed upon the chimes of freedom flashing | Bob Dylan
