The visit happened ahead of Dylan’s scheduled performance on Thursday at the Palazzo dello Sport, one of several Italian stops on his Rough and Rowdy Ways tour.

Leo has previously referenced Dylan in his own work, quoting Dylan’s unreleased anti-nuclear song, Go Away You Bomb, in the preface to a book titled Disarmed and Disarming: Peace Is a Gift.

“I hate you cause yer man-made and man-owned, an’ man-handled,” was the line quoted in the book’s warning to the world against rearmament.

The song was written in 1963 amid the Cold War, but was never recorded. The typewritten lyrics were unpublished until 2013 when they were discovered and put up for auction, according to the New York Times.

It was the second time Dylan had met a pope. In 1997 Dylan was invited to perform in front of Pope John Paul II and about 300,000 young people for the 23rd National Eucharistic Congress in Bologna.

Dylan played four songs including Knockin’ on Heaven’s Door, and reportedly climbed the stage mid-set to greet John Paul with a handshake and exchange a few words.

The then-Pope quoted Dylan’s hit Blowin’ in the Wind in his sermon to the crowd.
