I support both your answers. A wonderful morning today, I did weep a little bit, especially when the nephew of one of the chaps on our war memorial appeared.
I was in Whitehall at about 08:00 already suited and booted for the March Past
Had a chance to mingle before the Ceremony, and after, and I don't think I met anyone who could be called ordinary, but some very interesting people. The March Past finished Approx 13:00-13:15, so back to Kent mid afternoon.
