To mark the birthday of Bob Dylan, born today in 1941, let's watch the opening scene from "Don't Look Back" (1967), D.A. Pennebaker's documentary of Dylan's three-week 1965 concert tour in England. He's shown above holding cards that contain the lyrics, or variations thereof, from his "Subterranean Homesick Blues," which alluded to the political conflicts of the 1960s. Poet Allen Ginsberg is at the left of the screen. Joan Baez and Donovan also appear in the film.
