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.

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'd hear a tune in my head and the words would come. And then, very suddenly it just stopped. It seemed too stilted to try and learn how to write a song, to go to round robins and to learn things from other people on how to write a song. So I just stopped and did other things.

I've been obsessed with stopping people from blowing each other's brains out since I was ten.

If you don't have music, you have silence. There is power in both.

I've never had a humble opinion. If you've got an opinion, why be humble about it?

And my voice now is a struggle, it's a daily struggle to keep it up. Gravity has begun to fight the vocal cords the way it does with everybody. So I have a vocal therapist, and we record the sessions and I use them on tour every day.
