Dylan's an emperor with no clothes. Lennon turned on Dylan at some point (he trashed Dylan's Christian song "Gotta Serve Somebody"), but not after having gone through a "Dylan phase" during which he wrote songs such as "I'm A Loser" and "You've Got To Hide Your Love Away." John's "Yer Blues" has a Dylan reference.
The Leibovitz photographs from the time of this interview show Lennon as pale and hairy. He was in a heroin phase, I suspect.
