At 7 p.m., panting, I knocked on the door of room 201 of the Hotel InterContinental, Marseille, expecting it to be opened by Patrick Woodroffe, the man who has splendidly lit Rolling Stones gigs for the past 33 years, who would, I believed, hand over two tickets. With any luck, and on the strength of our slender acquaintance, I hoped these tickets would be upgraded to seats a little closer to the action than the ones we had paid quite enough for.
