Hold on now, this is verging on absolute nonsense.
Nomadds original post suggested that Maiden weren't as big/popular/legendary as Sabbath/Ozzy because Rod didn't learn from Sabbath/Ozzys managment.
That's utter nonsense, Sabbath and Ozzys place in the world is what it is, the music, the times, the fact that Ozzy was a very public figure and a lunatic at that. The fact that they are more known or revered by more people than Maiden has fuck all to do with decisions made by Roderick Smallwood, as Nomadd suggested.
You call Shadows response disingenuous. It was heavily sarcastic. Genuine sarcasm, in my reading of it.
We all know that Sabbath and Ozzy are better known/loved than Maiden in terms of the mainstream or non metalhead population or pure numbers or whatever. Suggesting that's Maidens managements 'fault' or defending that stance is beyond ridiculous.
