To love means you also trust.

I think I would have had an easier time of it if I had had training much earlier. Because when I got to the training, it was in my late 30s and I already probably had every bad habit a singer could have. In fact, it still goes on. It's un-training those habits and retraining new ones - the breathing, the relaxation, the tongue, the lungs, the everything.

I never pretended to be rock star. I would make a lousy rock star. I don't have the right voice for it. I don't have the "sex, drugs and rock 'n' roll" spirit. But the greatest flattery in the last couple of years is being called a "badass" by young singers.

My dread is for my show to be a nostalgia act. So the key to it is how do we keep it fresh?

It [my vocal] didn't sound like what I wanted to hear; the vibrato isn't what I liked anymore. So I got myself to an ear, nose and throat guy who does a lot of work with singers, and I was hoping there was a big wart on my vocal cords or something and they could scrape it off and I could have the voice I wanted. But he said, "No, for 71, that's your voice."

Someone had to change the world. And obviously I was the one for the job.

As long as one keeps searching, the answers will come.
