I've just recently been very into the Carol of the Bells. Depending on how you sing it, you can make it fun with lots of energy, or you can slow it down to give it a more haunting sound. Love, love, love that song!
My favorite Christmas carol is O Holy Night...actually that's just one of them...I love Christmas songs! I'll be Home for Christmas is another favorite.
In the Bleak Midwinter, my favourite version by Bert Jansch, although he doesn't sing all the verses.
Mine is Gaudete. It's in Latin, but utterly beautiful when sung well.
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.
