38. "Love Is a Long Road"
This churning rocker was co-written by Mike Campbell, who was inspired by a motorcycle he owned. "I was really into that frame of mind," the guitarist said. "This feels like a motorcycle shifting gears." Petty and Campbell recorded a demo that Petty described as "chaotic, with a lot of drum fills." Jeff Lynne polished out the kinks with the help of a hard-hitting performance by L.A. session vet Jim Keltner, and the finished track rivaled "Runnin' Down a Dream" in its sleek energy. "All of us had a hand in the arrangement," Petty said.
