The members of Black Sabbath may not be the rock miscreants they were in their 20s, but Ozzy Osbourne is fine with that, as it's brought the group back to what initially mattered to them in the first place -- the music. Osbourne spoke with the New Zealand Herald about the differences between the Sabbath of old and what's happening now and how age has brought some perspective.

The vocalist says, "What's different now is that none of us get drunk or stoned or any of that stuff. We're all clean and all in control of ourselves. We're not intimidated by each other. There are no arguments, and it's the way [that] it should be. But when we were kids, we had egos. When you're 21 and you get some success it takes a while to get your head around it."

Osbourne explains that the egos, the spoils of success, the alcohol and drugs, the groupies and everything else that comes with being in a successful rock band is hard enough for just one person to deal with, but having survived all that, he's happy to be rocking again with his longtime friends.

"We've done it all," says Osbourne. "So what it boils down to now is the music -- and that's what got us where we are in the first place. We have come through the other side, we're still able to work together, and that's where the enjoyment comes from. It's been a lot of fun making this record."

The singer says, "It's been more than 30 years since I really worked seriously with the guys. We had a try a few years back but nothing really came of it. But for some reason the timing is right and we've done about 15 songs." At present, the band is eying an April 2013 release for their new studio album.

Osbourne concludes, "Black Sabbath is very unique in the respect that nothing is formulated. It's very unpredictable. I just hope the people who have waited all these years aren't disappointed."
