An anecdote from Wikipedia:

In the November 1965 edition of Sing Out!, Silber wrote an article called "Open Letter To Bob Dylan".

    "I saw at Newport how you had somehow lost contact with people ... some of the paraphernalia of fame were getting in your way".[1]

Dylan did not like being told how to perform or how to write, and he didn't really like any criticism much either. He replied by telling his manager Albert Grossman that his songs were no longer available for publication in Sing Out!.

Eventually, in 1968, Silber retracted his criticism in the Guardian (US):

    "Many of us who did not fully understand the dynamics of the political changes ... felt deserted by a poet". "Dylan is our poet - not our leader ... Dylan .. is communicating where it counts."

The words quoted above are from page 314 of "No Direction Home: the Life and Music of Bob Dylan" by Robert Shelton.

In "Chronicles Volume One" (2004), Bob Dylan commented:

    "I liked Irwin, but I couldn't relate to it. Miles Davis would be accused of something similar when he made the album Bitches Brew ... what I did to break away was to take simple folk changes and put new images and attitudes into them."
