He has disappointed many, but not all. Madonna has finally exhibited at the San Siro stadium in Milan, after three years of abstinence, and after a swastika drawn on the face of Marine Le Pen in Tel Aviv, Istanbul and the nipple shown in the B-side exhibited in Rome, it was thought that Milan's performance was the culmination of the excesses. But no alluring as ever, sure, but well inside the lines, Madonna sang a ladder swinging between past and present, dance tracks and new interpretations, and he repeated the motto ''Italians do it better'' as he thanked everyone, including the public that still had to wait an hour before the Ciccone appeared on stage late.
