I've enjoyed every age I've been, and each has had its own individual merit. Every laugh line, every scar, is a badge I wear to show I've been present, the inner rings of my personal tree trunk that I display proudly for all to see. Nowadays, I don't want a "perfect" face and body; I want to wear the life I've lived.

In my early 20s, I had this idea that I was going to front a band, like Robert Plant of Led Zeppelin. I didn't just want to be the chick singing ballads about somebody breaking my heart. Everyone in the business said, 'Why don't you do what Olivia Newton-Jonn and Linda Ronstadt are doing?' But I wanted to sing as a powerful female who wasn't afraid to speak her mind or be sexual.

It's really hard to make records and concentrate and have a free mind, because I have this whole other life. If you don't have kids it's a whole other thing. I think you can be fifty and still have a rock and roll lifestyle; you can still perpetuate that.

People's lives change dramatically over such a long time period, and I think that if you're still vital, and you're still interested in writing and things like that, of course your music evolves and reflects where you are in your life.

When the first record came out, I'd go down to radio stations pretty much every day to get the record played, and I would walk in and they'd tell us how much they loved the record, but they weren't sure how much they could play it because they were already playing a girl.

I spent most of my adult life as someone's mother and the rest of my life trying to make sure that children are safe. So this to me is - we wrote Hell Is For Children in 1979.

It was very difficult when I was trying to figure out how to have a marriage and babies and do this at the same time. There was no handbook. You were making it up as you went along.
