Black Sabbath have been announced as one of the headliners for a British Summer Time gig in Hyde Park on July 4.
The band is supported by Soundgarden, Faith No More, Motorhead and Soulfly and other stages feature Gallows, Hell, Bo Ningen and Rise To Remain.
Ozzy says: "The first time I came to London I didn’t have a pot to piss in and I spent the advance I got for the first album on a new pair of shoes and some Brut aftershave. Returning almost 50 years on, we are doing a bit better for ourselves so I may even splash out on some new aftershave before taking to the stage at Hyde Park, the most beautiful park in London that has opened its gates to so many legends in the past. We are beyond honoured to be allowed to put on a show and hope that the Royals will enjoy it!"
