Black Sabbath singer Ozzy Osbourne says he can "die a happy man" after released reunion album 13.
It's the band's first-ever number one hit and topped the charts all over the world.
Ozzy says: "After 45 years it's kind of a hard thing to swallow. It's great. I'm not saying I don't want it to be number one – but I just don't understand why now.
"I wasn't really happy with the way it ended before, but this album has been received really well all over the world. I know I can now rest my head and die a happy man."
But he recalls worrying that the new material wasn't going to click with fans, after they played the first of two shows in Auckland, New Zealand.
"The first night they didn't really respond much to it," Ozzy says. "The second night they're all singing the lyrics with me. I'm going, 'I can't even remember them that good!'
"It's good for us as well to do new stuff, because you know, we're all tuned into Iron Man, War Pigs, Paranoid and all of the old classics. But it gives us as a band something refreshing to put into the show, so I'm just glad that people have bought into the new songs."
And there's only one thing he'd change about how things have gone musically – he'd prefer drummer Bill Ward to be part of the reunion. "We would love to have Bill back in the fold," he admits. "I wish him no harm. I still love him a lot. We all do – it would be great to have him back."
