Some singers worry about their voices to the point that they'll refuse to speak before a gig or cancel a show if they're feeling under the weather. Paul Di'Anno scoffs at these singers.

During a recent interview, the former Iron Maiden frontman talked about the difficulties some singers have hitting the notes after decades in the business, boasting that he doesn't do much of anything at all to safeguard his instrument -- and insisting that it's even improving with age.

"I've got tell you one thing, my voice is actually getting better," said Di'Anno, who can be seen onstage at a June 2014 performance in the video above. "I'm hitting notes I've never hit in quite a long time. And you know why? 'Cause I don't fuss about over it."

Continued Di'Anno, "Some people, they go, 'Oh, I've got a slight cough. Let's cancel the whole show. The whole tour's gonna be off.' If you look at my touring schedule, it's brutal normally. I do this five, six, seven days a week, something like that, and I'm still hitting those notes. And I'm really happy with what we're doing in the studio. I'm hitting notes Rob Halford can't hit anymore. So I'm doing quite well; I'm really happy ... I still smoke, I still drink. I still have it, mate."
