It was never supposed to happen this way. For years, the heavy metal universe existed in a state of stable equilibrium with two massive planets orbiting the same Birmingham sun: Black Sabbath and Judas Priest. They were the architects. The originators. But on July 22, 2025, that equilibrium shattered when the world lost Ozzy Osbourne.
Just weeks before his passing, something remarkable occurred that most fans are still trying to wrap their heads around. We're talking about the Judas Priest War Pigs cover. It started as a tribute. Then it became a haunting, posthumous duet that serves as the final studio recording of the Prince of Darkness.
If you think you know this song, you probably don't know the 2025 version.
The Birmingham Connection: Why War Pigs?
Honestly, the choice of "War Pigs" wasn't random. Since 2011, Judas Priest has used the original 1970 Sabbath track as their walk-on music. It’s a "rallying cry," as Rob Halford calls it. When those sirens start blaring over the PA system, the crowd knows the Metal Gods are about to hit the stage. It’s the signal for the road crew to put down the beers and for the fans to lose their minds.
But the 2025 recording wasn't just another cover.
Priest was "absolutely gutted," to use Halford's words, to miss the massive Back To The Beginning farewell concert at Villa Park in Birmingham on July 5, 2025. They were already contracted to play the Scorpions' 60th-anniversary show in Germany. You don't just bail on the Scorpions.

So, they went into the studio instead.
They recorded a "homage." It was intended to be a surprise video played on the big screens in Birmingham while they were stuck in Hannover. They didn't want to "mess with the song," so they played it straight—pure, heavy, and loud. The lineup featured Halford, Richie Faulkner, Ian Hill, Scott Travis, and notably, Glenn Tipton.
The Secret Recording Session
Here is where it gets crazy. After Priest released their version on July 2, Sharon Osbourne heard it. She loved it. She reached out to Rob with an idea that sounded like a fever dream: "Is there a way we can get Ozzy on it?"
Halford’s response? "You’re asking me? This is gonna happen!"
This wasn't just some AI-generated trickery. Ozzy actually went into the studio shortly before he died to record fresh vocal tracks specifically for this collaboration. It was a trade-off. One line from Ozzy, one line from Rob. Two of the greatest voices in the history of the genre finally sharing a track for the first time in their lives.

It’s heavy. It’s raw. It’s emotional.
Why the Judas Priest War Pigs Cover Hits Different
Most covers feel like a cheap imitation or a desperate attempt to stay relevant. This isn't that. When you hear Halford’s piercing precision against Ozzy’s signature, haunting drawl, it feels like the closing of a circle that began in the industrial smog of the West Midlands over fifty years ago.
- The Glenn Tipton Factor: Tipton, who has been battling Parkinson’s since 2008, plays on the track. This is a huge deal. His presence adds a layer of resilience that mirrors Ozzy's own fight with the same disease.
- The Tempo: Priest keeps the chugging, ominous pace of the original but injects it with that polished, "Painkiller"-era steel.
- The Vocal Trade-offs: Hearing them swap lines like "Generals gathered in their masses" creates a dialogue between the two pillars of metal. It’s a conversation.
The Charity Mission
Released officially as a charity single in September 2025, the song serves a purpose beyond just being a "cool collab." All proceeds go to The Glenn Tipton Parkinson’s Foundation and Cure Parkinson’s.
It’s a rare moment of genuine altruism in an industry often defined by ego. The two bands, once seen as rivals by some fans in the 70s, standing together to fight the very thing that forced their members off the stage.
What Most People Get Wrong About This Version
Some critics initially thought this was a live recording from a show they missed. It wasn't. It was a meticulously crafted studio tribute that accidentally became a memorial.

There's also a misconception that it was "Frankensteined" together from old Sabbath outtakes. While Sharon Osbourne has been known to be protective of Ozzy’s legacy, both Halford and producer Andy Sneap have been vocal about the fact that Ozzy’s vocals were recorded specifically for this "Charity Version."
It’s his final bow.
How to Listen and What to Look For
When you pull it up on Spotify or Apple Music, don't just listen to the riffs. Pay attention to the transition at the 3:40 mark. The way the guitars shift into that iconic "Luke's Wall" outro has a weight to it that the original—as perfect as it is—didn't have in 1970. In 1970, it was a protest against Vietnam. In 2025, it sounds like a protest against time itself.
Actionable Insights for Metal Fans
If you want to truly appreciate the depth of this moment in music history, don't just stream the song once and move on.
- Compare the two versions: Listen to the July 2 "Standard" Priest cover first, then the September "Charity" version with Ozzy. You can hear the difference in the mix and the energy.
- Support the cause: If you’re going to buy the track, do it through the official Ozzy or Priest websites to ensure the maximum amount of money hits the Parkinson's charities.
- Watch the "Giants In The Sky" tribute: At recent Priest shows, they’ve been playing their track "Giants In The Sky" with images of Ozzy on the screen. It pairs perfectly with the "War Pigs" cover as a full-circle experience.
The heavy metal community is often mocked for its obsession with the past, but the Judas Priest War Pigs collaboration proves that sometimes, the past has one more story to tell. It’s a loud, distorted, and beautiful goodbye.
