Di'Anno had previously insisted his voice was "getting better" and boasted he could hit the notes Judas Priest singer Rob Halford "can't hit any more." He said: "My voice is actually getting better - I'm hitting notes Rob Halford can't hit any more. And the reason is I don't fuss over it. I still smoke, I still drink - I still have it, mate."

Last year, Di'Anno told fans he was "pulling the plug" on his career but changed his mind and is currently working on an album with Architect Of Chaoz.
