Mike Campbell was more than Tom Petty’s bandmate. He was more than a friend, too. He was a partner who had an almost telepathic writing relationship with his famed frontman. Mike talks with Marc about crafting so many of those Petty hits, how they developed the Heartbreakers sound, what song he played that made Tom put him in the band, and why he wants to keep playing guitar and writing music into his 70s.  See omnystudio.com/listener for privacy information.
