Link to the BBC's live coverage. Almost certainly the last big anniversary with people who were there still here to be talked to. When it was the first one I can remember in 1974, O had little grasp of what it was about. My feeling is that the war was not a subject taught clearly at the time. It was a cultural remembrance filled with songs, and the one I knew referring to D Day was the D Day Dodgers, which I didn't really understand.
The World At War had been broadcast over the previous year but I doubt that I can have watched it avidly being 9 at the time. I'm not sure when it was repeated but I caught up with it then.
As a pacifist, I used to worry that such remembrances were too easily seen as just celebrations of bravery, but time has changed that, and it's more obviously a tribute to the tragedy. The windowing of those left by age and the normal trials of life has made it less about the glory, and more of the individuals.
