Osbourne joins his fellow original Black Sabbath members at the Whiskey A Go Go in Los Angeles on Nov. 11, 2011, to announce the reunion of the group. The group originally planned to record their first new album in 33 years and tour in 2012, but drummer Bill Ward (far left) dropped out of the reunion over contract issues. Instead, the band toured as "Ozzy and Friends" and began work on a new album late in the summer of 2012.
