The Paul Zollo interview is a particularly good one. I contacted him soon after it appeared in SONGTALK magazine and actually bought a small stock of the Dylan issue, as well as copies of some of the other issues. There were some fascinating interviews in them. Was MK one of the interviewees by any chance?
Dylan was accompanied to the Zollo interview, as I recall, by Elliot Mintz, who interjected a time or two. Mintz is a well-known PR person, who represented John Lennon or his estate for a while. I did meet him once outside one of Dylan's London shows and, subsequently, had a few direct dealings by phone and fax. He was courteous but cagey, especially about revealing too much. Sometimes, one had to divine the meaning behind his words by considering carefully how he expressed something rather than what he actually said. Other times, it was what he didn't say in a given situation that was the real clue. Mostly though, he said almost nothing but said it very well. He hasn't done Dylan's PR for years.
Zollo produced a book called "Songwriters on Songwriting", which is still available to the best of my knowledge.
