The most watched programme on the BBC after the news is probably 'Doctor Who.' What has happened is that science fiction has been subsumed into modern literature.

I look for the humanity in people however big the politics or oppressive the situation may be whether it's subsumed within a human being or between two human beings. I want to help us hold a mirror to ourselves.
When you sing with a group of people you learn how to subsume yourself into a group consciousness because a capella singing is all about the immersion of the self into the community. That's one of the great feelings - to stop being me for a little while and to become us. That way lies empathy the great social virtue.
