Metal Hammer magazine started the campaign last year and appointed Saxon singer Biff Byford as Global Metal Peace Ambassador and he helped gather the votes of fans.

It's not like pop music, where if the next song isn't good enough then forget about it; with our music, people will allow you to be shit sometimes, and that's one of the great things.
