On Thursday, July 24, the alt-rock musician — whose real name is Dominic Harrison — shared an Instagram post where he revealed his plans to play Black Sabbath's 1972 track "Changes" each night "for the rest of my life" following the rock icon's death on Tuesday, July 22 at age 76.

The lyrics for “Changes” were originally written by Black Sabbath bassist Geezer Butler, and the song appeared on the group’s 1972 album “Vol. 4.” In 2003, Ozzy and Kelly released a duet version of the song as a single. The song’s original lyrics are: “I feel unhappy, I feel so sad / I’ve lost the best friend that I ever had.”

Heavy metal legend Ozzy Osbourne dies at 76. The Grammy-winning Prince of Darkness long struggled with addiction, finally achieving sobriety in 2014.
