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 all-day event will also feature a host of major metal bands including Metallica, Slayer and Alice In Chains, with more names to be announced shortly.

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.
