Bob Dylan may be the Charlie Chaplin of rock n' roll. Both men are regarded as geniuses by their entire audience. Both were proclaimed revolutionaries for their early work and subjected to exhaustive attack when later works were thought to be inferior.

The Beatles never sounded intimidated by their idols. They never interpreted old rock; they simply played it as well and as joyfully as they knew how. On 'Rock 'n' Roll,' John Lennon does nothing but interpret old rock.
