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.”

Ozzy Osbourne has been remembered as a “pioneer,” a “fearless talent” and a “dear friend,” in an outpouring of tributes from fellow musicians and his former Black Sabbath bandmates following his death on Tuesday at the age of 76.

Mr Rumney, who plays in a band called Zero, said Black Sabbath had been a "big part" of his life since he was 12. He and his bandmates paid tribute to the momentous day Earth became Black Sabbath with a blue plaque in Workington in 2022.
