Although I can see why you thought that sounded like Diana Krall, it was actually Joni Mitchell (who wrote the song in the 60s). She performed this jazz version in 2000 on an album she did which was also called Both Sides Now. It was this recorded version that they played in the stadium.So beautiful.
Too bad they didn't get her to do it live.
No, Diana Krall didn't sing at the Ceremony I have watched it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
