These are very subtle things, of course, and I don't expect everyone to pick them up consciously, but I think that there is something there that you must be able to feel, there is an energy at work that I must trust my audience will be able to pick up at some level.
And when I perform on my own tour, I have to talk myself into going out on that stage every single night.
I think that we all know what evil is. We have a sense of what's evil, and certainly killing innocent people is evil. We're less sure about what is good. There's sort of good, good enough, could be better - but absolute good is a little harder to define.
