Fifty years ago, on July 25, 1965, the tousle-headed poet who had voiced his generation’s loftiest ideals of nonviolent protest came back to his spiritual home of many years, the Newport Folk Festival; strapped on an electric guitar for the first time in front of a band; and let loose a ripping sneer: “Aiiiii ain’t gonna wurk on Maggie’s fahm no mo’!” The congregation of folk music purists hissed, booed, threw bottles, and drove Bob Dylan from the stage, while the movement’s patron saint Pete Seeger had to be restrained from taking an ax to the power cables. And nothing was ever the same.
