Yesterday morning, at 8:30am, a full hour and a half before the gallery opened, I joined the queue which was already snaking around the National Gallery’s Sainsbury Wing. The hype in the press about this exhibition has been cranked up to fever-pitch and all advance tickets have now been sold. The only way to get in to see it is to queue on a morning in the hope of getting one of 500 tickets released every day. The anticipation and excitement in the queue were electric, and it was wonderful to be there with people who had gone to such great extremes to get tickets. One woman had come down from Nottingham and had got up at 3:30am in order to get to London on time to queue.
