kate. seem to be very strong and very loving. reporter: i think that is absolutely true. they are human beings like the rest of us. they have had ups and downs. notably with the death of the princess of wales and the divorce preceding that. i want to interrupt you. the 60-gun salute is about to be fired by the rifle regiment. this, of course, is the playing of the national anthem. there will be a salute fired in a moment. sorry, robert. reporter: it s a fantastic scene, martin. i think you can see the smiles in the crowds. it is beginning to rain. the union flags are waving. everyone seems to have a great time. although the umbrellas are up.
