He clarified that he’s not playing a full set with Black Sabbath, but rather will be “doing little bits and pieces with them.”Osbourne has dealt with his fair share of health issues in recent years. A 2019 accident resulted in spinal damage while the musician has also been diagnosed with Parkinson’s Disease. That eventually led to the shut down of his “No More Tours 2″ trek after multiple delays and the cancellation of his scheduled appearance at the Power Trip festival.”I am trying to get back on my feet,” remarked the singer. “When you get up in the morning, you just jump out of bed. I have to balance myself, but I’m not dead. I’m still actively doing things.”Black Sabbath Songs Ranked Worst to Best (Ozzy Osbourne Era)A total of 79 songs, including interludes!Gallery Credit: Joe DiVita
