Ozzy Osbourne and Black Sabbath announce final show

Ozzy Osbourne and Black Sabbath are reuniting for one last time, to play a fund-raising concert in Birmingham on 5 July.

The heavy metal pioneers will headline a spectacular one-day festival at Villa Park, featuring dozens of bands they inspired, including Metallica, Pantera, Slayer, Gojira and Anthrax.

The concert will mark the first time that Black Sabbath's original line-up - Ozzy Osbourne, Tony Iommi, Geezer Butler and Bill Ward - have played together in 20 years.

Osbourne, who has largely been forced to stop touring due to a combination of Parkinson's and spinal injuries, will play a short solo set before joining his bandmates.

His wife, Sharon, told BBC News he was determined to put on one final show.

"He's doing great. He's doing really great," she said. "He's so excited about this, about being with the guys again and all his friends. It's exciting for everyone."

However, she said the concert would definitively be the 76-year-old's final show.

"Ozzy didn't have a chance to say goodbye to his friends, to his fans, and he feels there's no been no full stop.

"This is his full stop."
