In an opinion piece published on Thursday in The New York Times, acclaimed songwriter Jason Isbell reflected on the legacy of his late hero and mentor, John Prine. Prine, widely considered to be among the greatest songwriters of his generation, and Isbell, who’s held in similar regard for his own generation, had a long history of friendship and collaboration during Prine’s life.

In the piece, Isbell—who went from a childhood fan of Prine’s to close friend and collaborator—reflects on the lessons he learned from Prine and puts his genius in perspective in a way that only a wordsmith of his stature could muster. Read a selection of excerpts from Jason Isbell’s John Prine tribute in The New York Times below, or read the full piece here.

A few years ago, my wife, Amanda Shires, was touring in Scandinavia with John Prine, and when they arrived in Sweden she saw him write “songwriter” on his customs form as his occupation. “When did you decide that it was OK to write ‘songwriter’ on these forms?” she asked him. “Today,” he told her. “I usually put dancer.”

John Prine was not a dancer. He was a songwriter and one of the best that ever lived, but he did love to dance. He danced around his house in Nashville with his wife, Fiona, danced in the driver’s seat of his beloved Cadillac and danced offstage every night, twirling an imaginary pocket watch. Once while performing onstage with John, I noticed him glance down past his Italian driving shoes to check the digital clock on the floor, and he saw me notice. He leaned in and whispered, “I wish we had more time. …

John was in his early 20s when he wrote “Hello in There” from the perspective of an old man sharing an empty nest with his lonely wife. Hearing him sing the song after decades of hard living and surviving numerous illnesses brought new meaning to the lyrics, now delivered by a man who had caught up with the character he created. John always said when he grew up, he wanted to be an old person. …

His songs sounded like they’d been easy to write, like they’d just fallen out of his mind like magic. He was praised for his dry humor and loved for his kindness and generosity. John had the courage to write plainly about the darkest aspects of the American experience in songs like “Sam Stone,” about a drug-addicted Vietnam veteran; “Paradise,” about the devastating effects of strip mining on a Kentucky town; and “The Great Compromise,” about his disillusionment with his country. Among his peers in the legendary Nashville songwriting community of the 1980s, his songs were the gold standard. 

Of all the things I love about John’s songwriting, my favorite is the way he could step so completely into someone else’s life. John had the gift and the curse of great empathy. In songs like “Hello in There” and “Angel From Montgomery,” he wrote from a perspective clearly very different from his own — an old man and a middle-aged woman — but he kept the first-person point of view. He wrote those songs and the rest of his incredible debut album while a young man working as a letter carrier in Chicago. “Angel From Montgomery” opens with the line “I am an old woman/named after my mother.”

I remember hearing his 1971 recording of this song for the first time and thinking, “No, you’re not.” Then a light bulb went on, and I realized that songwriting allows you to be anybody you want to be, so long as you get the details right. John always got the details right. If the artist’s job is to hold a mirror up to society, John had the cleanest mirror of anyone I have ever known. Sometimes it seemed like he had a window, and he would climb right through. …

And there was more to John’s life than music. John and Fiona Prine had a beautiful relationship, loving and balanced and kind. Fiona understood John better than anyone else. After Amanda and I were married, Amanda started asking all the couples we knew, “What’s the secret to staying together?” John and Fiona gave the same answer, and it was the best one we’ve heard so far: Stay vulnerable. John remained vulnerable in love and in his work. He never played it safe.

When I was a baby, my 17-year-old mother would lay me on a quilt on the floor of our trailer in Alabama and play John Prine albums on the stereo. Forty years later, my daughter would call him Uncle John as he bounced her on his knee. My wife and I would sing his songs with him in old theaters or sometimes in his living room. In the summer, we’d all eat hot dogs with our feet dangling in his swimming pool. Now he’s gone and my heart is broken.

This week, John Prine danced off this stage and onto the next one, and I like to think he’s somewhere sharing a song and a cocktail with all the friends he outlived. 

Rest in peace, John Prine. You are loved.
