Back to this new photograph. It was taken by Linda McCartney, who must have been standing practically next to Macmillan as he looked down from atop his stepladders. Apparently no photo exists of either Macmillan from his unique vantage point or, indeed, the police officer who was on hand to stop the traffic whilst the Fabs traversed the crossing. Imagine if such an image was to turn up; an elderly St. John's Wood resident passes and during a house clearance they stumble upon a shoebox with a load of Kodak slides in it. It would surely make the Holy Grail look like a Skegness ashtray.
* I wonder who was driving that bus?
