Ozzy Osbourne will be performing the final Black Sabbath reunion concert at his own pace.

On the SiriusXM channel Ozzy’s Boneyard, the legendary rocker revealed during his Ozzy Speaks segment that he won’t be performing a full set with Black Sabbath during their final reunion concert in July titled “Back to the Beginning.”

“I’m not planning on doing a set with Black Sabbath but I am doing little bits and pieces with them,” Ozzy, 76, said, via Billboard on Sunday, Feb. 16. “I am doing what I can, where I feel comfortable.”

“I am trying to get back on my feet,” the “Crazy Train” singer continued. “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.”

Despite several health setbacks, Ozzy is still determined to put on a show for fans, even if expectations need to be lowered.

This revelation comes less than two weeks after his wife Sharon told The Sun that he can no longer walk because of Parkinson’s disease, which he was diagnosed with in 2003. “He’s very happy to be coming back and very emotional about this,” she told the publication.

“Parkinson’s is a progressive disease. It’s not something you can stabilize. It affects different parts of the body and it’s affected his legs,” Sharon, 72, continued. “But his voice is as good as it’s ever been.”

Black Sabbath announced their final concert, which will take place on July 5 in Birmingham’s Villa Park, in February.

“It’s my time to go back to the beginning … time for me to give back to the place where I was born,” Ozzy said in a statement. “How blessed am I to do it with the help of people whom I love. Birmingham is the true home of metal. Birmingham for ever.”

Joining Black Sabbath onstage will be Metallica, Slayer, Pantera, Gojira, Halestorm, Alice in Chains, Lamb of God, Anthrax and Mastodon.

Guns N’ Roses’ Slash, Smashing Pumpkins’ Billy Corgan, Korn’s Jonathan Davis, Limp Bizkit’s Fred Durst, Wolfgang Van Halen and Rage Against the Machine’s Tom Morello will also join together as as super-band for the concert.

The proceeds from the reunion concert will benefit Cure Parkinson’s, Birmingham Children’s Hospital and Acorn Children’s Hospice. Tickets are on sale now via Live Nation.
