Charles III might be the King of England, but Ozzy Osbourne will always be the Prince of Darkness. And in honor of the rock legend's life and legacy following his death July 22, the Royal Family's official army band put its own spin on one of Black Sabbath‘s biggest hits.

King Charles III’s guards broke tradition to celebrate Ozzy Osbourne’s legacy. The Band of the Coldstream Guards performed a rendition of the Black Sabbath song “Paranoid” during the Changing of the Guard ceremony at Buckingham Palace on Wednesday,

Louis, who was born during Ozzy's first marriage to Thelma Riley, paid tribute to his dad by wearing a purple tie with skull and crossbones designs. This was in reference to Black Sabbath's famous imagery. His siblings, Jessica and Elliot, weren't seen at the funeral.
