You know that feeling when a song hits so hard it actually hurts? That's the vibe of this track. If you've ever typed "who sings i can't live" into a search bar, you're likely chasing a specific kind of heartache or a massive, glass-shattering high note. But here’s the thing: people often get the title slightly wrong, usually referring to the iconic "Without You." The hook, "I can't live, if living is without you," is so powerful it has basically rebranded the song in the public consciousness.
Music history is full of these sorts of overlaps. Honestly, the song has been covered by hundreds of artists, but only a handful of people truly own it. To understand who sings it, you have to look at three very different eras of music: the 1970s rock scene, the 90s diva explosion, and the weird, tragic origins that most people completely forget about.
The Tragic Origins of the Song Everyone Knows
Before the world-famous versions existed, there was Badfinger. This is the part that usually surprises people. Pete Ham and Tom Evans, members of the British rock band Badfinger, wrote the song in 1970. It wasn't some calculated pop hit. It was a "Frankenstein" creation. Pete had a song called "If It's Love" that wasn't quite working, and Tom had a chorus that felt like a standalone piece. They fused them together.
The result was "Without You," appearing on their album No Dice. It’s raw. It’s gritty. It lacks the polish of later versions, but it carries a heavy weight. Sadly, the history of the song is marred by the fact that both Ham and Evans later took their own lives, largely due to legal and financial battles within the music industry. When you hear the original, that desperation isn’t just performance. It’s real.
Harry Nilsson: The Man Who Made It a Global Phenomenon
If you ask someone from Gen X or the Boomer generation who sings "I can’t live," they will immediately name Harry Nilsson. Nilsson was a legendary figure in the 70s—a favorite of The Beatles and a man with a vocal range that defied logic. He heard the Badfinger track at a party and initially thought it was a Beatles song. When he realized it wasn't, he decided to record it for his 1971 album Nilsson Schmilsson.

Nilsson’s version is the definitive one for many. It’s the one that won a Grammy. It’s the one with the soaring, slightly ragged peak that feels like a man falling apart in real-time. He took a rock ballad and turned it into an epic, cinematic experience. It topped the Billboard Hot 100 for four weeks in 1972. If you're looking for the version that sounds like a smoky 70s lounge meets a stadium rock finale, this is it.
Mariah Carey and the 90s Vocal Masterclass
Then came 1994. This is where most Millennials and Gen Z listeners enter the chat. Mariah Carey released her cover of "Without You" as the third single from her massive album Music Box.
Look, Mariah didn't just cover the song. She rebuilt it. Her version is widely considered one of the greatest vocal performances in pop history. While Nilsson’s version was about the raw emotion of the break, Mariah’s was a showcase of sheer technical brilliance and "power ballad" energy. She released it globally, and it became an absolute monster on the charts, specifically in the UK and Europe.
Mariah actually chose to cover it after hearing it in a restaurant. She felt she could bring a different perspective to it. She was right. Her version reached number three on the Billboard Hot 100, but its legacy is arguably bigger than its peak chart position. It’s the version that inspired a decade of American Idol contestants to try (and usually fail) to hit those specific notes.

Wait, What About Air Supply?
This is a common point of confusion. Many people search for "who sings i can't live" and expect to find Air Supply. They have a song called "Even the Nights Are Better" with similar lyrics, and another massive hit called "Making Love Out of Nothing at All."
However, Air Supply never actually recorded the most famous "Without You." They have a song called "I Can't Live a Day Without You" (which is different) and their general "soft rock" vibe often gets muddled with the Nilsson version in people's memories. If you are thinking of a male duo with high-pitched harmonies, you might be mixing up your 80s ballad groups.
The Others: From Kelly Clarkson to Heart
Because the song is such a vocal "Mount Everest," many powerhouse singers have tackled it.
- Shirley Bassey: Delivered a version that feels like a James Bond theme. Pure drama.
- Kelly Clarkson: Frequently performs it live. Her version leans into the soulfulness of the lyrics.
- Heart (Ann Wilson): Brought a rock edge back to it, bridging the gap between Badfinger and the diva era.
- Leona Lewis: Her cover was a staple during her rise to fame, emphasizing the vulnerability.
Why Does This Song Still Rank So High?
The longevity of "Without You" comes down to the universal nature of the lyric. "I can't live, if living is without you" is the ultimate hyperbole of love. It’s dramatic. It’s a bit much. But in the middle of a breakup? It’s the only thing that makes sense.

Technically, the song is fascinating because of its structure. It moves from a quiet, almost whispered verse into a chorus that requires an immense amount of "belt" or "head voice" strength. Most singers can't handle the transition. That’s why the famous versions stay famous—they represent the gold standard of vocal ability.
Identifying the Version You're Looking For
If you’re trying to find the exact version stuck in your head, check these markers:
- Does it sound like a 70s record with a piano and a slightly grainy male vocal? That’s Harry Nilsson.
- Is it a massive, polished 90s production with incredible high notes and runs? That’s Mariah Carey.
- Is it a bit more acoustic, maybe a little sadder and "band-oriented"? You’re looking for the original Badfinger version.
- Does it have a disco beat? You might be listening to the T.G. Sheppard country-pop crossover or one of the many Euro-dance remixes from the late 90s.
The Technical Reality of Singing It
From a technical standpoint, the song is a nightmare for most vocalists. The chorus hits a high note that must be held with power, not just touched upon. In the key of the Mariah Carey version, she’s hitting notes that most professional singers struggle to sustain without straining. This is why the song is often used as a litmus test in singing competitions. If you can sing "Without You," you can sing anything.
Actionable Steps for Music Lovers
If you’ve been caught in the "who sings i can't live" rabbit hole, here is how to actually enjoy the depth of this song:
- Listen to the Badfinger original first. Understand the pain of the guys who wrote it. It changes how you hear the "glossy" versions.
- Compare the Nilsson and Carey versions back-to-back. It’s a masterclass in how two different genres (70s Soft Rock vs. 90s R&B/Pop) can interpret the same emotional core.
- Check out the live versions. Mariah Carey’s live performances of this song during her Music Box tour are often cited as her "peak" vocal era.
- Avoid the knock-offs. There are many "karaoke" versions on streaming services that aren't labeled well. Always check the artist name under the track title to ensure you’re getting the authentic recording.
There isn't just one answer to who sings this song. It’s a baton that has been passed from a tragic rock band to a 70s icon, and finally to a global superstar. Each one added a layer to why we still search for it decades later.
