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.

How you looked was not important. It was what you did and how you did it. Decide to do it and then do it the best way you can.

The Berlin Wall go down, that was the most wonderful thing that could happen, absolutely. I celebrated with everybody in Berlin that day when the Wall was down.

I left the table where there were important people and had lunch with my husband and a few friends. The reception was organised in my honour, so it was rather amusing.

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

I grew up thinking that singing was my security.

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.
