I'd have said Dickinson was up there, however he's so much more than a metal legend, he's a fencer, pilot, businessman: he's a god damn genius. Also, I think he's rather tame compared to Halford, Ozzy, Iommi, Dio etc, especially when you factor his other projects, plus the fact that he's quite well spoken for and also a Eurosceptic Tory to boot. Not the most rock and roll thing ever but as a Eurosceptic Right Winger rocker / part time metalhead myself it's fine by me! He's certainly a unique man.
