April 30 marks the 60th anniversary of Bob Dylan‘s 1965 U.K. tour that produced the documentary Dont Look Back. He began the tour with a show at the City Hall in Sheffield, ending at Royal Albert Hall in London that May.

Throughout the tour, filmmaker D.A. Pennebaker gathered footage to compile into a documentary. Joan Baez appears for much of the film, as does Dylan’s manager Albert Grossman, his road manager Bob Neuwirth, Donovan, and Alan Price of The Animals.

There are a lot of great scenes from the film, but one that stands out is a particularly volatile interview between Bob Dylan and TIME reporter Horace Judson. Then, Judson was a newly appointed London arts and science correspondent. He was trying to work his way up to an editor position eventually. So, to put in his time, he took an assignment to interview Bob Dylan. He had already been interviewing the Beatles and the Rolling Stones. All this even though, according to Judson, he didn’t even like rock music that much.

In a blog post from the fansite Expecting Rain, a 1998 email from contributor Michael J. Kahn explained that Horace Judson was his professor at George Washington University. Judson was a historian of molecular biology, and is remembered more for his contributions to science than to music journalism.

Kahn said that, after watching Dont Look Back for the first time, he recognized his professor. Sure enough, after bringing it to Judson’s attention, Judson sat down with Kahn and told his side of the story.

“The interview lasted about 30 minutes and was fairly normal, at least as normal as a 1965 Dylan interview could be, until Bob just went nuts and started yelling at [Judson],” the email explained. “He just sat there befuddled, he didn’t know what to do […] he said he wasn’t angry, just surprised. Afterwards he was disappointed that Pennebaker decided to only use the last 10 minutes of the interview.”

Judson long believed that Bob Dylan’s outburst was a calculated tactic to make the film more exciting. “He has no doubt in his mind that Grossman and Pennebaker instructed Bob to conduct himself in that way to spice up the film,” the email added.

Kahn’s post concluded by claiming that some Bob Dylan fans on the site have the wrong idea about Horace Judson. According to Kahn, he was just trying to do his job as a reporter. Instead, he was met with hostility that was never really explained.

“Judson didn’t give a s–t about what Dylan was BSing about, he was just doing his best to try to interview the guy who he was assigned to interview,” Kahn explained. “He was hardly some representative of the establishment trying to bring down the counter culture revolution.”
