Ozzy Osbourne‘s family is mourning the late rock legend following his death at age 76 on Tuesday. On Thursday, the Black Sabbath frontman’s daughter Kelly Osbourne expressed her grief with a reference to the British heavy metal band’s 1972 ballad ‘Changes’ on her Instagram Story.

On July 22, Kelly Osbourne, along with mom Sharon Osbourne, siblings Jack Osbourne and Aimee Osbourne, as well as half-sibling Louis Osbourne, from the singer's previous marriage to Thelma Riley, released a statement confirming the Black Sabbath lead singer's death.

Osbourne, who battled Parkinson’s before his death, sat onstage in a black leather chair as he performed for the 42,000-person crowd. He sang five songs by himself, before he was joined by his former bandmates for four Black Sabbath songs.
