I'm never nervous when I go to meet heads of state. I feel they should be nervous, because they are the ones who'll be held accountable for the lives their decisions will impact the most.

Particularly conservative Christians, I was very angry that they were not involved more in the AIDS emergency.

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

Pop music often tells you everything is OK, while rock music tells you that it's not OK, but you can change it.

Dream up the kind of world you want to live in. Dream out loud.

I'm home a lot. Because I live in Ireland, we can live under the celebrity radar. I might go missing for a whole year.

To be one, to be united is a great thing. But to respect the right to be different is maybe even greater.
