Black Sabbath was formed in Birmingham, England in 1968 by Tony Iommi, Bill Ward, Ozzy Osbourne and Geezer Butler. With the release of their groundbreaking self-titled debut album in 1970, the band defined what Heavy Metal was and what it would be. A lot happened in the following decades with Ozzy being fired in the late 70s, Bill Ward leaving in the mid-80s and only Tony Iommi was the group's constant member, being part of every album they released. They reunited a few times in the 80s and 90s, but the most enduring reunion was really from 2011 to 2017, when the band announced their return and even recorded a new studio album called "13" (2013). At first, the drummer Bill Ward would be part of the reunion but then he decided to leave. There were claims that it was for health issues, because of his heart condition but also that it was for financial reasons, since he claimed the share he would receive wouldn't be good enough. So then the group proceeded with Ozzy's drummer Tommy Clufetos as a touring member and "13" was recorded with Rage Against The Machine's Brad Wilk. Now in an interview for his own internet show "The Madhouse Chronicles" (Transcribed by Blabbermouth), Ozzy said that he would like to do a final Black Sabbath show with Bill Ward. He even said that it would be cool if it was a surprise show in some small club. Ozzy says he would love to do a final Black Sabbath concert with Bill Ward "I can't remember why Bill didn't do it (The reunion). I've gotta be truthful. It wasn't really Black Sabbath because Bill wasn't there. I mean, if you had Ginger Baker playing with The Beatles, it wouldn't be The Beatles." "Yeah (We did the final show in Birmingham), but I was sad that Bill wasn't there. I mean, I mean, Tommy (Clufetos), my drummer , did a great job, but he ain't Bill Ward." "(That's unfinished business) because it wasn't Black Sabbath that finished it. It's unfinished. If they wanted to do one more gig with Bill, I would jump at the chance. Do you know what would be cool? If we went to a club or something unannounced and we just got up and did it. We started up in a club," Ozzy Osbourne said. Ozzy had canceled his farewell tour "No More Tours 2" due to health issues a few years ago. He will be inducted this year into the Rock and Roll Hall of Fame as a solo artist. He was already inducted in 2006 as a member of Black Sabbath. https://www.youtube.com/watch?v=E2NyPbT2WoY&pp=ygUbYmxhY2sgc2FiYmF0aCAxOTk5IHBhcmFub2lk
