Black Sabbath guitarist Tony Iommi said he thinks bandmate Ozzy Osbourne was "determined" to play the group's farewell show and "really just held out" to do so weeks before his death.

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.

Kelly Osbourne is mourning the loss of her father Ozzy following his death on Tuesday. Osbourne posted a brief message to her Instagram stories on Thursday afternoon. “I feel unhappy I am so sad,” she wrote. “I lost the best friend I ever had.”

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.

As tributes continue to pour in, two of Ozzy Osbourne's children — Jessica and Louis — have honored their late father in subtle ways after the former Black Sabbath frontman and legendary rocker died on Tuesday,
