Monday’s appearance marked Ozzy Osbourne’s first time on stage since 2019, when he joined Post Malone on their collaboration, “Take What You Want”, at the American Music Awards. Prior to that, his last full performance was on New Year’s Eve in 2018, per Rolling Stone. Since then, The Ozzman has faced a number of health setbacks, including a staph infection and fall that stunted his No More Tours 2 farewell tour, originally launched in 2018. In addition to the limitations posed by the pandemic, Ozzy also revealed a Parkinson’s Disease diagnosis and recently overcame a bout of COVID. Even in the face of these mortal hindrances, the heavy metal icon has long maintained that he will never retire.

“You know the time when I will retire? When I can hear them nail a lid on my box. And then I’ll f***ing do an encore. I’m the Prince of Darkness,” Ozzy said in 2020.
