I don't let my religious world get too complicated.

God is in the slums, in the cardboard boxes where the poor play house. God is in the silence of a mother who has infected her child with a virus that will end both their lives. God is in the cries heard under the rubble of war. God is in the debris of wasted opportunity and lives, and God is with us if we are with them.

Music can change the world because it can change people.

As a rock star, I have two instincts, I want to have fun, and I want to change the world. I have a chance to do both.

The great moments of rock 'n' roll were never off in some corner of the music world, in a self-constructed ghetto.

Sub-Saharan Africa is also home to 400 million of the world's poorest people.
