Ozzy Osbourne is saying goodbye to the stage after performing what has been billed as his final show with the original members of Black Sabbath.

Ozzy Osbourne may have given his final performance, but he hasn’t yet given fans his final writings - or “Last Rites,” as he punningly puts it. His new memoir of that name will come out this fall, Hachette Book Group announced Thursday.

On July 5, Ozzy performed his final concert — titled “Back to the Beginning” — with his band Black Sabbath. It was the first time the singer had reunited with the group in 20 years.
