We're nondenominational. I come from Northern Ireland, and we've had religious wars for years. I didn't want to create an illusion that my God is better than your God. So our show is a spiritual show, not a religious show.

There are clearly many good politicians who are guided by religious belief, so the mix can work. But there's a line to be drawn. It would be hugely dangerous for a country's laws to be set by the scriptures, and particularly those of the expansionist religions.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
