In 2009, for a profile for "Sunday Morning," CBS News' Anthony Mason asked Petty what it was like to write with Dylan.
"He's just as good as you think he would be," Petty said. "I was there for a reason, so I had to get past his Bob-ness, you know?"
"His Bob-ness? Well, how do you get past that? I mean, it's gotta be intimidating, sitting down with him."
"Well, it is. But he's a person."
