The original line-up of heavy metal legends Black Sabbath, including Ozzy Osbourne, will play together for the first time in 20 years at a one-off concert on July 5 in Birmingham, England, organisers said on Wednesday.

Ozzy Osbourne will reunite with all of the original members of Black Sabbath for the first time in 20 years, in a gig that will be his last and that’s being billed as the “greatest” heavy metal show ever.

Black Sabbath will be reuniting for a performance in Ozzy Osbourne's hometown of Birmingham, U.K.. Osbourne, 76, has been battling Parkinson's disease for years, but the Prince of Darkness will not let that keep him from the stage.
