Today, as we mourn Ozzy's passing, we should remember that Black Sabbath's legacy extends far beyond their game-changing sound. They also established the principle that heavy music required equally heavy visuals, and proved that album art could be as transgressive as the music itself.

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.”

Kelly Osbourne paid tribute to her late father, Ozzy Osbourne, by sharing a special version of the Black Sabbath song Changes. She called him her "best friend.

After performing the Black Sabbath 'Changes' at their farewell show in Birmingham, Yungblud has released the live cover, with all proceeds going to charity.
