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.

With the exception of instrumental tracks, there are a total of 20 songs from Sabbath's albums with Osbourne that never made the cut live, according to Setlist.fm. Therefore, there may have been a time where a song was played for a specific event that wasn't a concert.

The performance, called "The Back to the Beginning," will cap off an all-day event featuring sets from several iconic heavy metal acts.
