The heavy metal band Judas Priest has released a new version of “War Pigs” with the late Ozzy Osbourne to raise funds for charity in the fight against Parkinson’s disease.

Ozzy Osbourne, former frontman of Black Sabbath, was diagnosed with the degenerative neurological disorder in 2019 and passed away at the age of 76 on July 22, just weeks after a farewell concert at Villa Park in Aston, Birmingham — just a stone’s throw from the area where he grew up.

Judas Priest, who were formed in Birmingham in the 1960s, decided to release their own version of Black Sabbath’s “War Pigs” for a good cause after they were unable to join other metal bands at the July 5 concert due to prior commitments.

Band member Glenn Tipton, who has also been diagnosed with Parkinson’s disease, plays guitar, while Rob Halford and Ozzy Osbourne alternate on vocals.

The song was originally conceived as a tribute video to Osbourne and Black Sabbath, before the band suggested turning it into a charity single.

Proceeds from the sales will go to the Glenn Tipton Parkinson’s Foundation and the Cure Parkinson’s research center.
