One of its members, Dave Harrison, from Chester, says: "The significance of Bob Dylan in the 1960s is that he changed popular music forever, expanding the limits of what pop songs could be about.
"But the greatest revolution was his attitude, particularly in the mid-60s when he played with an electric backing band after years of performing solo with an acoustic guitar.
"Many regard his Manchester Free Trade Hall gig on May 17 1966 - film of which is included as part of Scorsese's documentary - as a defining moment in rock history when a heckler shouts at Dylan, "Judas".
"Confronting his accuser, Dylan rallies his band by saying "Play f--- loud!" and launches into a ferocious version of his anthemic Like A Rolling Stone.
"This is the point at which popular music ceases to be the cosy tunes of the Hit Parade but instead transforms into that rebellious, challenging and glorious noise we call rock 'n' roll.
Forty-three-year-old Tim Dalton remembers the night even though he was but a tot. He was being babysat while his mum and dad, Karl and Jenny, both ardent folkies, attended the Free Trade Hall gig - and remembers the debate that raged around him for days afterwards.
Tim, now senior lecturer in Popular Music Studies at Liverpool John Moores University, believes that Dylan's influence is still reverberating through today's music.
"I think he is crucial to modern pop. You only have to look at his influence on local bands such as the Coral and The Basement who even take their name from one of his albums, The Basement Tapes. In fact we've just had freshers week and at least three of the 18-year-old kids on this course turned up wearing Dylan T-shirts so you can see how his influence now spans three generations. In fact, I had hippy parents who were really into Dylan so I grew up listening to the likes of Maggie's Farm."
He believes that Dylan was responsible for what can be called an "epistemic break" in which an event takes place causing a rift in time and space that changes things forever.
In a pop music context, it happened when the black civilian Meredith Hunter was knifed to death by Hells Angels when the Rolling Stones appeared at Altamont bringing a bitter symbolic end to the peace and love era of the 60s.
