MAIDEN WOULD NEVER BE WHO THEY ARE WITH OUT DICKINSON. HE IS ONE OF THE BEST METAL VOCALISTS.  BUT DIANNO WAS GREAT ALSO. MAYBE HE DIDN'T HAVE THE BEST VOICE BUT HE KNEW HOW TO USE IT AND HE USED IT WELL. ALMOST LIKE BON SCOTT. KILLERS IS STILL ONE OF THE GREATEST METAL ALBUMS OF ALL TIME AND FIRST MAIDEN ALBUM HAS SOME GREAT THINGS ON IT ALSO.
