This clip from D.A. Pennebaker's 1965 documentary Don't Look Back captures a famous moment between Donovan and Bob Dylan in a London hotel room. Donovan begins at 00:28 by playing his acoustic guitar and singing To Sing for You, delivering a gentle, earnest folk performance while Dylan, Allen Ginsberg, and others listen attentively in the room. At 02:15, Donovan passes the guitar over to Dylan, who tunes it slightly before launching into an intense performance of It's All Over Now, Baby Blue.
What makes the interaction so compelling is the contrast in presence and style between the two young artists. Donovan's sweet, fingerpicked balladry is charming, but when Dylan takes over, his sharp strumming and biting vocal delivery completely command the space. It is a remarkable piece of music history caught on film, showing two 1960s icons sharing a tense yet candid off-stage encounter at the height of the folk era.
