After the infamous "Judas!" heckle during a 1966 concert at Manchester Free Trade Hall (not the Royal Albert Hall, as is commonly believed), Dylan responds, "I don't believe you. You're a liar!" He then turns to the band and shouts, "Play fucking loud!" Then comes the thundering opening chords of "Like a Rolling Stone".
"My Back Pages", which is essentially him looking back at his Protest Song phase and going "...Yeah, valid points all, but damn, I was young and naive." Written when he was 23.
Ah, but I was so much older then, I'm younger than that now!
In a wider sense, the fact that he's kept making new music and, the occasional Seasonal Rot and He Changed, Now He Sucks attitude notwithstanding, kept moving for his entire career. As one reviewer wrote about "Love And Theft", "It's not the best album anyone's ever made, but it just might be the best thirty-first album anyone's ever made."
