Bassist Geezer Butler revealed that Ozzy Osbourne wants Black Sabbath to reunite for “three or four songs” at his final concert. Ozzy hopes the original four members of Sabbath can get back onstage together one last time for the occasion. Butler mentioned that Ozzy is eager to play and suggested a farewell concert where they could perform a few songs together. It remains uncertain if guitarist Tony Iommi and drummer Bill Ward would be willing to participate, but Ward has expressed interest in playing with Sabbath again. Despite past estrangements, Butler and Ozzy are now in regular communication and appear to be on good terms.
