Saturday night, on what would have been Petty's 67th birthday, Dylan showed his famed versatility, playing a surprise cover of the late-legend's "Learning to Fly" at a show in Colorado.
To honour him, he played one of his best-known songs, 1991's 'Learning to Fly'.
Petty died on October 2 after suffering a cardiac arrest.
The 76-year-old spoke emotionally about Petty after his death.
Here's some not-so-amazing concert footage - why is it at an angle? - with decent enough audio of the magical moment in question.
Following Petty's death on October 2, Dylan said of Petty in a statement to Rolling Stone, "It's shocking, crushing news".
"It's shocking, crushing news". "I thought the world of Tom". Petty and Dylan, of course, were famously members of The Traveling Wilburys along with George Harrison, Roy Orbison and Jeff Lynne.
The pair also performed together on Dylan's True Confessions tour in 1986, which was later captured in the concert film Hard To Handle.
