One of the biggest hits of the late 80s was more of a happy accident than a well thought out masterpiece. The iconic Tom Petty track “Free Fallin’” was the result of a random jam session between Petty and fellow musician / Traveling Wilburys member Jeff Lynne, also the frontman from ELO.

Tom Petty came up with the song while trying to make Lynne laugh, as he described in a recent interview with Billboard:

“(Jeff) and I were sitting around with the idea of writing a song and I was playing the keyboard and I just happened to hit on that main riff, the intro of the song, and I think Jeff said something like, ‘That’s a really good riff but there’s one chord too many,’ so I think I cut it back a chord and then, really just to amuse Jeff, honestly, I just sang that first verse. Then he starts laughing. Honestly, I thought I was just amusing Jeff but then I got to the chorus of the song and he leaned over to me and said the word, ‘freefalling.’ And I went to sing that and he said, ‘No, take your voice up and see how that feels.’ So I took my voice up an octave or two, but I couldn’t get the whole word in. So I sang ‘freeee,’ then ‘free falling.’ And we both knew at that moment that I’d hit on something pretty good. It was that fast. He had to go somewhere, and I wrote the last verse and kind of just polished the rest of the song and when I saw him the next day I played him the song and he was like, ‘Wow, you did that last night?’ And I was like, ‘Yeah.’ And he said. ‘We’ve got to go cut this,’ and we just took off to Mike Campbell’s studio where we knew we could get in and get it done that day. So we went in and made the record that day.”

Petty later compared songwriting to fishing saying “you’re not necessarily going to get one every time you try…you either caught a fish or you didn’t. If you did, there’s one in the boat; if you didn’t, there’s not. But you’re going to go back and keep your pole in the water. That’s the only way you’re going to get a bite.”
