It's the people and the cause that matter and right now there's an important need, which is bridge-building. I wanted to support the cause of humanity, because that's what I always sang about. Music can be healing, and with my history and my knowledge of both sides of what looks like a gigantic divide in the world, I feel I can point a way forward to our common humanity again. It's a big step for me but it's a natural step. I don't feel at all irked by the responsibility — I feel inspired.
