Rush is one of my favorite bands and Uriah Heep's "Demons and Wizards" is one of my very favorite albums of the 70's. That being said, 'Child in Time' is simply majestic, easily the best of the three songs you mention.
All three bands are great but Uriah Heep are my faves. 1. July Morning. 2.
Child in Time. 3. Xanadu.
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.
