Black Sabbath singer Ozzy Osbourne's sisters recall their final interactions before his death at 76, noting he was frail but still joking before a farewell performance in England.

The musician’s death came just 17 days after he performed his final concert with Black Sabbath at England’s Villa Park, a swan song he’d been planning for months. “That show meant everything,” the source says. “It brought his career full circle.”

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.
