Yeah, I was in the phase for the last ten years or so where every record I made I said OK, that's the last one, I don't want to record anymore, I don't want to do this any more, I don't want to have a public life.

The new record started out being about loss, but it's morphed into being about how relationships go on even though one person is not in a body anymore.

I think any young person who is going into the same field as their parent whose parent has been very successful, it's complicated.And it was complicated for me.

Self-expression without craft is for toddlers.

On the plane, an eight-year-old with an excess of testosterone keeps running across my feet. Finally I grab him by his T-shirt and say, very sweetly, 'Listen, darling, if you don't stop trampling me I'm going to make you sit on my lap while I tell you my entire life story. Including a lot of details about drug rehab and my divorce.' He goes back to his seat.

I found it was really impossible for me to write songs when I couldn't sing.

He [Johnny Cash] was so fragile. We invaded Iraq in March, and he died in September. And because his health was so fragile, he couldn't take the controversy of making a public statement against the war. He knew that people were rabid. They attacked me mercilessly after I did the press conference with Musicians United to Win Without War. He knew that he couldn't tolerate that.
