Dylan introduced the band to marijuana that night, and McCartney later joked that he had discovered “the meaning of life.” When he performed with an electric band at the Newport Folk Festival in July 1965, some members of the folk community reacted with outrage. Many had embraced Dylan as a symbol of the folk revival and saw the electric performances as a rejection of that identity. They were like, ‘Hey, he’s forsaken the folk,’” Harrison said.
