Credo: Lorna Luft

Actress and singer, 56

I believe...

I owe my theatre etiquette to my mother [Judy Garland]. I make sure I show up on time and listen to directors – discipline is one of the gifts she left me.

Working in the theatre is never boring. When you work with TV people, they have the luxury of being able to say, "Let's do that again." You can't do that in theatre.

I just went into the family business. I never really considered anything else.

I had nothing to compare my childhood with. It was what it was. Reporters are more intrigued by my mother than the public – people just come up and say,"I really enjoyed you in this, that or the other." They know about my mom, but they've already heard about that.

I've embraced who I am. I've embraced my legacy as well as Natalie Cole or Lisa Marie Presley. There are a bunch of us and we're friends. We're card-carrying members of a little club of legendary children.

I'm lucky to be working, especially when there are so many people not working and about to lose their jobs.

There is light at the end of the tunnel with our new president. It was pretty bleak for a while and we are in dire straits. It took George Bush eight years to get us into this, so you can't expect Barack Obama to get us out in four. But it can't get any worse.

My children have no interest in showbusiness. My daughter is in college in San Diego and my son is a stockbroker. I want them to do whatever makes them happy, and that's what they're doing.

I'm boring, I really am. I like to relax because I'm on the road so much. I lie around, I watch TV and I read magazines. Right now I'm in love with Brothers & Sisters and Mad Men. I'm also a news junkie.

I'm proud that 'The Wizard of Oz' is in my family. It's a movie that is so loved by millions of people around the world – it will go on and on.
