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.

Ozzy Osbourne has announced that the original members of Black Sabbath will play a concert together for the first time in 20 years.

At 76 years old, Ozzy has faced serious health challenges, including seven surgeries in the past five years and a long battle with Parkinson’s disease, which he was diagnosed with in 2003. His ongoing medical issues have already delayed his and wife Sharon Osbourne’s planned move back to the UK.
