Ozzy Osbourne‘s Parkinson’s disease has progressed to the point where the musician is no longer able to walk. Speaking on his SiriusXM program Ozzy’s Boneyard this week, Osbourne discussed what fans can expect from his final live performance,

Osbourne has received a number of accolades through career, including a Grammy for Best Metal Performance in 1994. In 2006, he was inducted into the Rock and Roll Hall of Fame with his Black Sabbath bandmates, then again as a solo artist last year by Hollywood actor Jack Black.

Ozzy Osbourne and Black Sabbath are reuniting for one last time, to play a fund-raising concert in Birmingham on 5 July. The heavy metal pioneers will headline a spectacular one-day festival at Villa Park, featuring dozens of bands they inspired, including Metallica, Pantera, Slayer, Gojira and Anthrax.
