One of the most beautiful duets of the 1970s is hiding in plain sight. “Fly Away,” John Denver’s wistful hit of late 1975, features a second voice woven all through the record — echoing his lines, answering his phrases, lifting the choruses into the sky. That voice belonged to Olivia Newton-John, at that moment one of the biggest stars in the world, with number-one singles of her own. Her name appears nowhere on the single. It was a duet the record business made invisible, and everyone who heard it knew anyway.
A Song for the Woman in the High-Rise
Most Denver hits sing from inside the country life — the farm, the mountain, the open road. “Fly Away” is different: it sings about someone still trapped outside it. The song’s subject is a woman in the city whose days have gone, in Denver’s unforgettable phrase, “soft and cloudy,” whose dreams have gone dry, who finds herself crazy for the sounds of the sand and the sea. She is, in the song’s gentle refrain, getting ready to fly away — toward silence, toward nature, toward a life that feels like her own.
Paul Nelson, reviewing the parent album Windsong for Rolling Stone, spotted exactly who this woman was. “The singer acknowledges his average listener in ‘Fly Away,'” Nelson wrote, observing that by 1975 Denver albums had become as common in city apartments as potted plants — both of them symptoms of the same urban longing for something green and alive. It was a perceptive and slightly acid reading: the song is a mirror Denver held up to his own audience, the millions of apartment-dwellers who bought his records precisely because their lives looked like the one in the verses.
That is what lifts “Fly Away” above the standard escape fantasy. Denver does not mock the woman or promise her a simple salvation. He lingers on her weariness — the way a life can be comfortable and still feel like a slow defeat — and offers flight not as tourism but as rescue. Of all his nature songs, it is the one most honest about what his listeners were actually fleeing.
Notably, the song never tells us whether she goes. There is no departure scene, no arrival at the shore — only the readiness, the gathering of will. That suspended ending is why listeners have argued about the song for fifty years: is the flight a move to the country, an exit from a deadening marriage, or something darker and more final? Denver leaves the question hanging in the melody, and the gentleness of the arrangement lets each listener answer it privately. It may be the least resolved hit he ever had, and the most adult.
The Voice That Wasn’t Credited
The recording itself is where the song becomes a story. Denver cut “Fly Away” for Windsong, the 1975 album that would top the Billboard 200, and he invited his friend Olivia Newton-John to sing with him. Her contribution is no token harmony. She echoes and answers Denver throughout, her voice appearing in passages where his falls away, so that the record plays as a genuine dialogue between two singers — exactly what Record World praised on release, noting the “unmistakable Denver vocal charm with the added bonus of Olivia Newton-John joining in on the chorus.”
And yet the 7-inch single credited Denver alone. The reason was industrial, not personal: Denver recorded for RCA, Newton-John for MCA, and two competing labels had little appetite for sharing a star. Rather than fight the legal wrangle, the pair simply left her name off. The oddity is that Newton-John was no anonymous session singer hiding from obscurity. By late 1975 she had already topped the charts with “I Honestly Love You” and “Have You Never Been Mellow,” and she was, like Denver, a country-pop crossover star navigating an industry that wasn’t quite sure which shelf she belonged on. The two were firm friends, bonded partly by that shared in-between status — pop stars in a country mode whom the genre purists never fully claimed.
Listen closely and the arrangement tells the song’s story a second time. Denver sings the verses as an observer describing the woman’s stalled life; Newton-John’s voice drifts through the choruses like the woman’s own inner weather — the part of her already halfway out the door. When her lines surface in passages where his voice drops away entirely, the effect is less like a harmony than a haunting: the escape the lyric imagines is already singing back. It is an extraordinarily sophisticated piece of record-making for a supposedly simple singer, and it depends entirely on the interplay the label credit denied. Generations of listeners who never saw the television performance simply assumed the second voice was some gifted studio singer. It was, in fact, one of the most famous women in music, moonlighting in secret for a friend.
Consider what each singer brought into the studio that year. In 1975 Newton-John was in the middle of an astonishing run: “I Honestly Love You” had topped the American chart in 1974, “Have You Never Been Mellow” followed it to number one in 1975, and she had collected Grammy Awards along the way. Denver, meanwhile, was the CMA’s Entertainer of the Year with the number-one album in the country. Under any normal business logic, a collaboration between them would have been billed in letters a foot high and marketed as an event. Instead, because of the label divide, it slipped out disguised as a solo record — a superstar duet smuggled past the accountants. There is something fitting about the subterfuge: a song about a woman quietly preparing to slip away from her life was itself slipped quietly past the industry.
Television, happily, could not keep the secret. Denver and Newton-John performed “Fly Away” together on his Rocky Mountain Christmas television special, standing side by side in full view of the country, and the easy chemistry between them became one of the special’s standout moments. Radio listeners might not have known whose voice haunted the record, but anyone watching that broadcast could see the duet for what it was.
Two Weeks at the Top of a Different Chart
Released as a single in November 1975 with “Two Shots” on the B-side, “Fly Away” peaked at number 13 on the Billboard Hot 100 — a respectable showing, but not the whole story. On the adult contemporary chart, where Denver was close to royalty, it spent two weeks at number one in early 1976, his sixth chart-topper on that listing. It also reached number 12 on the country chart and number 13 in Canada, with a number two peak on the Canadian adult contemporary chart and a showing on the Canadian country chart besides. Three formats, three audiences, one whisper of a record.
The pattern tells you something about how Denver’s music actually worked in the world. The rock audience measured him by the Hot 100 and found him soft; the adult contemporary audience — older, quieter, and enormous — made him a fixture. “Fly Away,” a gentle song about a gentle despair, was built for exactly the listeners who crowned it. Following “I’m Sorry” and “Calypso” in Windsong‘s remarkable run of singles, it confirmed that the album was one of the defining records of Denver’s peak years.
A Friendship That Outlasted the Charts
The duet was one chapter in a longer mutual admiration. Newton-John had recorded her own version of “Take Me Home, Country Roads,” carrying Denver’s song to audiences he hadn’t reached, and the two remained close for the rest of his life. When Denver died in October 1997, his experimental plane crashing into Monterey Bay, Newton-John was among those who honored him most publicly: she presented his posthumous induction into the Colorado Music Hall of Fame. Decades later, in her memoir Don’t Stop Believin’, she wrote that she still felt Denver near her when she performed — naming him, alongside her parents and Karen Carpenter, among the “spirit guides” she asked for support before a show. “They’re gone, but their love never dies,” she wrote.
Both voices on “Fly Away” are silent now — Denver gone in 1997, Newton-John in 2022, at 73 — and the song has gathered a poignancy its makers could not have intended. Since her death, the record has circulated anew among listeners discovering that the “backup singer” on a favorite old single was Olivia Newton-John all along. A record about the wish to fly away, sung by a man who would die at the controls of his own aircraft, answered by a friend who outlived him by a quarter-century and spoke to him still. But the record doesn’t need the biography to work. It needs only those two voices, one credited and one not, trading lines about a woman in a high-rise dreaming of the sea — proof that in 1975, the loveliest sound on American radio was a duet that officially never happened.
