Ozzy Osbourne will come out of touring retirement and reunite with the full Black Sabbath lineup for the first time in 20 years.

The Prince of Darkness will play his final show in July, with Black Sabbath, Metallica, Slaye, Anthrax, and more featured on the high-profile bill.

Ozzy Osbourne spoke about his health on his radio show, saying he "can't walk" but is grateful to still be alive ahead of his Black Sabbath reunion show.
