Abc's katie couric sat down with these legendary ladies on the set of betty's show "hot in cleveland." They could turn the world on with their smiles. You got spunk. Reporter: Their apartment battles. This is my apartment. Reporter: Their vibrating bed. Reporter: Long before carrie and the gang, there were those other girls. Mary, rhoda, phyllis, sue ann and georgette. The female leads of "the mary tyler moore show." Yesterday the fierce five played by actresses mary tyler moore, valerie harper, cloris leechman, betty white and georgia engel were together again to film an episode of "hot in cleveland" and to reminisce. Can I just say truly sincerely i am so thrilled and honored to be with all of you ladies. ♪ Love aall around no need to waste it ♪ when I saw mary richards drive in that mustang to that tv station in minneapolis, i thought, wow, I can have a career too. And what is it like for you all working together after 40 years? Yeah, it really is heaven and none of us has changed. Well, we've done the best we can. Gravity has taken over a little bit. When you think back on the show that really started all of this, why do you all think it resonated so much? So reflected life, katie. It reflected women. And then, mary, that ever popular question, how come a girl like you I married? How come you're still single? IN THE '70s WOMEN, YOU Women were living differently. Out! Out! You know, I think one of the things, the writing was fantastic. But if you don't put on your hats you can't have any dinner. But your characters were also just so fun and funny and interesting and imperfect. Tell me why you think people were so attractive first of all to rhoda. Because they recognized themselves. Eat something. I can't. I got to lose ten pounds by 8:30. A friend of mine once said, mary is who you wish you were. Rhoda is who you probably are and phyllis is who you're afraid you'll become. We try to be very truthful in our family. You're not her aunt. What about sue ann nivens, what was it about her, betty. Well, she was the neighborhood nymphomaniac. They don't make men like this anymore. They don't make dip like this anymore. Georgia, what about georgette? She was the slowest one of the group but they had fun -- sometimes having the wisest thing coming out of georgette's mouth. Surprise! It's not a surprise party, georgette. She expected it. Oh. Expected! You were kind of an idiot savant. Weighing on the minds of these old friends, the recent disclosure that valerie harper has an inoperable brain tumor. We're progressing, i certainly see what's ahead. What could possibly be tomorrow. In fact, I'm hoping I get through friday. But I've got to tell you, my dear, my money is on you. Her positiveness and her -- everything is on the up side and that's 90% of it. Where did you find valerie -- a lot of people honestly would get into bed and put the covers over their heads. Don't go to the funeral until the day of the funeral. Don't miss your life while you're feeling good and you can do things. You can have your time to cry. You can really, you know, in grief or say why me and rage. Let it be there. Go throughd then move on from it. Reporter: The lasting leg sieve the ladies isn't lost on those who have followed in their footsteps including the cast members of "hot in cleveland." When I was young I kept thinking, god, it would be so much fun to grow up and be in a show where you got to play with your girlfriends which is what they did. So it's sort of like a dream come true. Reporter: This may be the last time the five will be together but the mood of the reunion wasn't sad, it was a celebration of old friends and a shared path that made tv history. As we sit around on the set, running lines and it's just, you know, makes me think what a lucky woman you are. How fabulous to be working with the people who are your very good friends. It's so true. That you become even more than family. You become -- because it's something that you can't explain to anybody. It's just there. And I look around at these girls and I just -- me too. My heart fills with love. Look at you, sweetheart. Happiness and love and celebration and what life really is. ♪ You might just make it after all ♪ an unforgettable reunion for sure. So much love and laughter among these ladies. We'll have much more on "nightline" and, of course, on "katie." Now back to you in new york. Thank you, katie, so much for that. We cannot wait. What do you say after seeing that? What do you say? Chemistry. The love, the love. I agree. A group hug. I love that. Ended that way again. And they fall right back into it which is really the best.
