Vanity Fair’s James Wolcott recalls when Bob Dylan unexpectedly showed up to meet upstart punk Patti Smith in 1975 in an upcoming memoir. “I was present when one of [Smith’s] cryptic idols paid a call,” Wolcott writes in “Lucking Out: My Life Getting Down and Semi-Dirty in Seventies New York.” “And I wrote it up for [the Village Voice] as if witness to a superpower summit.” Wolcott says Dylan’s presence was “unknown to many” in the audience. When Dylan went backstage to offer “encouragement” to Smith, “There was a sexual excitation in the room,” according to Wolcott. “Dylan, the verdict was unanimous, is an intensely sexual provocateur.” The book also charts the rise of CBGB and habitues like Joey Ramone, Debbie Harry, Tom Verlaine and David Byrne. An acolyte of The New Yorker’s Pauline Kael, Wolcott also writes that more than opinions were routinely passed around by Kael’s inner circle of movie mavens at the time. “Some reviewers traded off girlfriends,” he writes.
