I think he had a different view of Madonna back in the old days, he saw her as someone very much "her own self", and he also said a phenomenon like Madonna could never happen again. I for one am very glad he doesn't like her. Very VERY glad.
Madonna was known simply as the Smelly American back then. When she came to the Hacienda for The Tube, she did her dance number without deodorant and stunk the club out. Her performance was instantly forgot, but her armpits were nominated for a Fac number!
