I had a galvanised voice: I could sing through a 105 fever or a flu or a root canal or anything that you could throw at me.

I miss singing every day. I can't sing anymore. My voice doesn't work. I have Parkinson's disease, and it sometimes takes my words away from me.

I didn't know why I couldn't sing - all I knew was that it was muscular or mechanical. Then, when I was diagnosed with Parkinson's, I was finally given the reason. I now understand that no one can sing with Parkinson's disease. No matter how hard you try. And in my case, I can't sing a note.

You don't forget you have Parkinson's disease, believe me, especially in the shower. If you are not paying attention, you fall down.

The thing I like about singing duets is that I get things out of my voice I never get singing by myself.

You don't want people who have never had to deal with adversity - you want people who have been able to deal successfully with adversity. That's what adds to society. Those are going to be the hardest-working, best people.
