If you’re ever nervous about performing on stage, so is Geezer Butler about the upcoming farewell show

On July 5th, Ozzy Osbourne, Tony Iommi, Geezer Butler, and Bill Ward—the original members of Black Sabbath—will reunite at Birmingham’s Villa Park. Known as “Back to the Beginning”, the event promises closure as well as nostalgia, culminating a half-century of heavy metal with a benefit concert that will raise money for charities that help children and Parkinson’s patients. Although it’s a heartfelt farewell, emotions are nuanced behind the scenes.

I’m already having palpitations. In fact, I had a nightmare last night. I dreamed everything went wrong on stage, and we all turned to dust. It’s important that we leave a great impression, since it’s the final time that people will experience us live. So it has to be great on the night.

It was just a nightmare luckily!
