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.

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.

The Osbourne family is expected to look at the sea of tributes when the cortège reaches Broad Street at around 1pm. Crowds of people, many wearing Ozzy Osbourne T-shirts and holding posters and other tributes, are already waiting behind metal barriers all along Broad Street.
