Joni Mitchell wrote "Both Sides, Now" at twenty-three, somewhere above the clouds, reading Saul Bellow's Henderson the Rain King on a plane. A passage early in the novel sent her to the window, and what she saw there — the same clouds she had romanticized as a child, now blocking the light and grounding planes — became the seed of a song she would spend the rest of her life living into. She wrote it fast. She performed it live at The Second Fret in Philadelphia on November 17, 1966, before most people knew her name. She gave it away before she recorded it herself. And then, thirty-one years later, she recorded it again, and the second version turned out to be a different song entirely.

The giving-away part matters. Shortly after Mitchell wrote it, Judy Collins recorded "Both Sides, Now" for her 1967 album Wildflowers. Collins released it as a single in October 1968, and it reached number eight on the US pop charts by December, winning Collins a Grammy for Best Folk Performance in early 1969. Mitchell reportedly disliked the recording, despite the attention it brought her. There is something clarifying in that detail: even at twenty-three, Mitchell knew exactly what the song was doing, and Collins' version, fragile and ornamented with harpsichord, was playing a different instrument than the one Mitchell had in mind. Mitchell's own version finally appeared as the closing track of her second album, Clouds, in May 1969, recorded at A&M Studios in Hollywood with engineer Henry Lewy. She played it in open D tuning, capo at the fourth fret, in F# major, her voice still bright and searching, the guitar spare beneath it. By the time Clouds was in stores, more than a dozen artists had already covered the song.

What Mitchell's 1969 version understood, and what made it the one that carved itself into cultural memory, was the quality of its uncertainty. The narrator looks at clouds, love, and life from both sides and arrives not at wisdom but at the same confession three times over: "I really don't know" clouds, or love, or life, "at all." For a generation of listeners in their twenties, that refrain was a form of solidarity. The not-knowing felt honest rather than defeated. It felt young, in the best sense: open, unresolved, still willing to be surprised. Clouds won Mitchell a Grammy for Best Folk Performance in 1970, and the song became one of her signatures, covered by Frank Sinatra for his 1968 album Cycles, by Willie Nelson as the title track of a 1970 album, and eventually by well over a thousand artists across every conceivable genre. Rolling Stone ranked it number 170 on its 500 Greatest Songs list in 2004.

Then came the second version. In 2000, Mitchell re-recorded "Both Sides, Now" for her seventeenth studio album of the same name, with the orchestra arranged and conducted by Vince Mendoza and co-produced by Larry Klein. The album, conceived as a suite tracing the arc of a relationship from first feeling to final acceptance, placed the song at its close. The 2000 version is in D major, the voice dropped and roughened by decades of smoking, the strings swelling beneath her in a way the 1969 guitar never could. It is a reckoning. The same words now carry the full weight of a life lived through them. Where the young voice was searching, the older one is certain of the uncertainty, which is a different thing altogether. The album won two Grammy Awards in 2001, for Best Traditional Pop Vocal Album and Best Instrumental Arrangement Accompanying Vocalist.

The 2000 version found its defining cultural moment three years after its release. In Richard Curtis's Love Actually (2003), Emma Thompson's character retreats to her bedroom after opening a Christmas present she had hoped would be a gold necklace and finding instead a copy of Mitchell's 2000 album. Her husband, played by Alan Rickman, has given the necklace to someone else. She sits alone, and Mitchell's orchestral version of "Both Sides, Now" plays as Thompson's face does the work that the lyrics have already done: the slow comprehension of how much you didn't know, how much you still don't. The scene has no dialogue. It doesn't need any. The song is the scene. In the character's line earlier in the film, Mitchell is described as "the woman who taught your cold English wife how to feel," and the movie earns that line by the time the bedroom door closes.

Nearly two decades later, the song found another life in Siân Heder's CODA (2021), the Best Picture-winning film about a hearing daughter of deaf parents. In the film's climax, Ruby, played by Emilia Jones, performs "Both Sides, Now" as her audition for Berklee College of Music, and mid-song begins signing the lyrics to her deaf family watching from the audience. Mitchell herself gave her approval for the use. The two film deployments are almost perfectly inverse: in Love Actually, the song is about what has already been lost and understood too late; in CODA, it is about what is just beginning to be understood, and the signing turns the song's private reckoning into something offered outward, shared across a divide. The same words, the same melody, doing opposite emotional work.

What keeps "Both Sides, Now" alive across generations is the architecture Mitchell built into it: a song that tells you it doesn't know, written by someone young enough to mean it with hope and old enough, in the second recording, to mean it with acceptance. Most songs are fixed at the age of their making. This one grew a second version, and the distance between the two recordings — the same open tuning, the same modified I-IV-V progression, the same lyric, the voice thirty-one years deeper — is where the real meaning lives. You hear it differently at twenty-three than at fifty, and Mitchell knew that, because she was the proof.
