There were wonderful moments when I was singing for the first time in the Olympia Theatre and I was pregnant with my son, which was very, very strange for a singer.

One of the most wonderful memories in my life was when I sang at the Opera House in Sydney. I will never forget that. It is one of the most beautiful Houses I have ever sung in my life.

UNICEF has made the most rewarding thing that I have ever done in my life.

Once I was condemned to three months' absolute silence. As I could not speak, I wrote a book.

Every time I would open my mouth to sing, everybody was paying attention to me. It became a habit.

I always try to see things with children's eyes. Are they happy? Sad? What do they need? Everywhere I went, I realized that children are society's victims ... We have a duty to speak to political leaders, to influence people to give these children a better future.

I thought it was respectful to each country to sing in their language.
