Black Sabbath guitarist Tony Iommi revealed how they prepared the setlist for the farewell tour in an interview with Guitar World.
He revealed surprising statement about Ozzy Osbourne’s voice as follows:
“We knew we wanted to play the classics, so we didn’t really play anything off the final album, ’13.’
I would’ve liked to have played some of the songs that we haven’t performed for many years like ‘Hole in the Sky’ or ‘Symptom of the Universe,’ but we could only do songs that Ozzy could still sing.
That’s no disrespect to him. When we recorded those songs originally 30 years ago, the keys were so high there was no chance in hell that he could still hit those notes. But it would’ve been nice to have had them in the set.”
