This past October 20th would've been the late, great Tom Petty's 69th birthday. His daughters Adria and Annakim Petty -- along with Heartbreakers keyboardist Benmont Tench looked back at the complexity of their respective father and friend. Adria spoke about how Petty parented his daughters, telling Classic Rock magazine. "He had no guide book for a normal, healthy family environment, or how his role as a father should be defined. That confused him and troubled him towards the end of his life. He felt like he hadn't delivered for us as much as he could have done. The flip-side is that music is where he found his purpose and where he was happy. You don't really want to begrudge someone that either, if that's the reason they're on the planet."

Younger daughter Annakim went on to say, "He was really into surrealism, and dad raised me from an early age to be very arty. But there was something very grounding about how connected he was to his craft." When asked how he would've responded to being considered a musical force for the ages, Adria said, "He would have loved it. He was always: 'Look at me, I'm a living legend.'" Annakim added: "He had enough miles on him to be called an icon."

It was after his 1996 split with wife Jane -- the mother of his daughters -- that Petty, then in his late-40's, began using heroin. Keyboardist Benmont Tench, who had kicked his own coke habit in the late-1980's recalled, "When I realized that he was taking heroin, I was really frightened and I was really sad. I was a little mad at him, which is irrational, because as a recovering drug addict I know that that s*** gets you. You're basically f***ed once it gets you. You don't have any control any more. But I was frightened for him and there was nothing I could do."

Regarding the Heartbreakers' final tour in 2017 celebrating their 40th anniversary, Tench remembered, "He never said it was the last tour, he said it was the last big, long tour, playing big places. By the end of it he was like: 'Damn, we can just take a couple of years and come back and play stadiums. I'm never breaking this band up!' He was charged. And that's how he was before those last gigs."

At the time of Tom Petty & The Heartbreakers' 1999 Echo album, which was recorded in the aftermath of Petty's divorce and heroin issues, guitarist Mike Campbell shed light on how the band proceeded during a rough patch in Petty's personal life: "He is the guy that's writin' the songs, and he's the leader of the group, and it was hard for him to focus for awhile, understandably. I think, actually, in a way, working on the record probably helped him at that point, just to sort of get back into focus as to what he wanted to do. But maybe some of that feeling did kind of carry over into the project a little, and it did slow us down. Y'know, there were times when months would go by and he'd just go, 'Y'know, I just can't work today. I got too many things that I'm dealing with right now.' And we'd go 'Okay.' Y'know, we'd just wait."
