John Denver never had a hit with “Leaving on a Jet Plane.” His own single sank without a trace, and the song belongs, in the public memory, to three other voices entirely. Yet no song mattered more to his career. Written by a 23-year-old unknown during an airport layover, handed to the biggest folk group in America, and carried to number one in the last weeks of the 1960s, it was the song that bought Denver his solo career — a farewell he gave away, which then refused to leave him.
A Song Written in an Airport Layover
In 1966, Denver was Henry John Deutschendorf Jr., a young singer from Roswell, New Mexico, trying to survive in the Los Angeles folk scene. He had dropped out of architecture school at Texas Tech, joined the Chad Mitchell Trio, and was still years from fame. During a layover at Washington National Airport, he wrote a song about the peculiar ache of the traveling life: the packed bags by the front door, the taxi idling in the dark, the lover asleep upstairs. Its original title was blunt to the point of comedy — “Babe I Hate to Go.”
Denver recorded it that year for John Denver Sings, a rough, self-made demo album of songs from his live set. He pressed a handful of copies and gave them out as Christmas presents — the closest thing to a release the song had. But the demo sat in the orbit of Milton Okun, the powerful folk producer who worked with both the Mitchell Trio and Peter, Paul and Mary, and who would soon become Denver’s own producer. Okun saw what the young singer had. He persuaded Denver to retitle the song “Leaving on a Jet Plane” in 1967, and then he did something more consequential: he carried it to Peter, Paul and Mary.
Denver himself always insisted the song was smaller and more personal than its later mythology. In one of his BBC Radio specials, he explained that it did not conjure up airliners for him so much as “the simple scenes of leaving” — bags packed by the door, a taxi in the early morning, and the thought of leaving someone you care for very much. It is a song built entirely out of that doorway moment, and it was written before Denver had any career to travel for. The leaving was imagined first; the life caught up later.
The song also arrived in Denver’s life at the one moment it could do him the most good. He was the least-known member of his own circle: Okun produced Peter, Paul and Mary, the most commercially successful folk act in America, and Denver was a close friend of the trio as well as a client of their producer. When Okun brought them the young man’s airport song, he was performing the classic folk-scene act of patronage — handing a standard-in-waiting from an unknown writer to the interpreters who could make it immortal. Denver understood his debt precisely. He was “fortunate,” as he put it, to have them record it. Fortunate hardly covers it: the trio’s version would do more for his career than anything he could yet do for himself.
Peter, Paul and Mary Take It to Number One
Peter, Paul and Mary recorded the song for their 1967 album Album 1700, one of the defining records of the folk boom’s commercial peak. At first it was simply a strong album track, and in 1967 it circulated on a promotional EP. But by 1969 the trio’s label, Warner Bros.-Seven Arts, sensed its potential and released it as a single that September.
The timing was perfect, in a way nobody planned. The single climbed through the autumn and reached number one on the Billboard Hot 100 in December 1969 — the penultimate number-one single of the entire decade. It spent three weeks atop the easy listening chart, topped the chart in Canada, and reached number two in both the United Kingdom and Ireland in February 1970. Cash Box praised it as “stunning material” with “an especially fine arrangement.” It became Peter, Paul and Mary’s biggest hit, and their only number one — the farewell song was the peak of a career built on protest anthems, children’s songs and Dylan covers. United Airlines, catching the mood, used the song in commercials in the late 1960s and early 1970s, sealing its place in the era’s soundscape.
The trio’s recording is a small masterpiece of arrangement: three voices braiding around the lyric, Mary Travers’ lead carrying the ache while Peter Yarrow and Paul Stookey cushion it, the whole thing over in three and a half minutes. Released with “The House Song” on the B-side, it had the unhurried confidence of a song that had already been sitting, fully formed, in the group’s repertoire for two years — first cut for Album 1700 in 1967, then floated on a promotional EP, then finally, patiently, promoted to a single. Few number ones have had so long a fuse.
Denver, meanwhile, re-recorded the song for Rhymes & Reasons, his debut studio album for RCA, and released his own version as a single in October 1969. It failed to chart — the only version of the song ever to do so, perversely, was the trio’s. His recording career had been made possible in part by the trio’s recording of his song, yet as a performer he could not buy a hit with it. In 1973 he recorded it a third time for John Denver’s Greatest Hits, and it is that warm, settled version that has appeared on most of his compilations ever since — the composer’s own reading, arriving years after the song had already done its work. That Greatest Hits album itself went to number one, meaning the definitive Denver performance of “Leaving on a Jet Plane” reached the public at the very moment he had become the star the song had once only promised he might be.
The Vietnam Shadow
Denver did not write the song about the Vietnam War, and he said so. But in 1969, America was sending young men across the Pacific by the hundreds of thousands, and a song about a dawn departure, a waiting lover and the words “don’t know when I’ll be back again” could not help but be heard as a soldier’s farewell. Critics such as Tom Breihan, writing Stereogum‘s “The Number Ones” column, have noted how the Peter, Paul and Mary recording was widely interpreted as a protest song about impending deployment — less a statement the trio made than a meaning the moment imposed.
That double life is part of the song’s durability. Denver’s lyric is scrupulously private: no war, no politics, not even a destination. It is all threshold and taxi light. Precisely because it names nothing, it could be claimed by everyone standing in a doorway in 1969 — the touring musician, the drafted infantryman, the student leaving for good. The song became the sound of American departure at the exact moment departure was the national experience.
There is also something valedictory in its chart position. The trio’s single was the second-to-last number one of the 1960s; within days, Diana Ross and the Supremes would close the decade’s chart story with “Someday We’ll Be Together.” The sixties — the decade of the folk revival, of coffeehouses and hootenannies — effectively ended with a folk trio singing a young unknown’s goodbye. Peter, Paul and Mary never reached number one again. The song was their summit and their farewell at once, which is perhaps the most “Leaving on a Jet Plane” outcome imaginable.
Lawsuits, Covers and an Enduring Farewell
The song kept generating stories long after the sixties. In 1998, Canadian singer Chantal Kreviazuk recorded a version for the film Armageddon, and it reached number 33 in Canada. Stranger still, in the 1980s Denver sued the British band New Order, arguing that the wordless guitar break in their 1989 single “Run 2” was based on his melody. The case settled out of court, and Denver received a co-writer credit — an unlikely footnote linking the gentlest of folk ballads to Manchester post-punk.
The measurements of its stature are striking. On Billboard‘s all-time Hot 100 ranking compiled for the chart’s 60th anniversary, the Peter, Paul and Mary recording sits at number 565 — modest-looking, until you remember it is competing with every hit since 1958. Denver’s own recording has earned Gold certification in New Zealand and Silver in the United Kingdom, streaming-era honors for a single that originally failed to chart at all.
But the real legacy is biographical. Denver’s solo contract with RCA grew, in part, directly out of Peter, Paul and Mary recording his song: it proved the unknown trio singer could write a standard. Within four years he would be the biggest-selling artist in America, with “Take Me Home, Country Roads,” “Rocky Mountain High” and “Annie’s Song” still ahead of him. All of it traces back to a layover, a demo album given away at Christmas, and a song about leaving that he could not hold on to — and that has never really left.
