GRETA VAN SUSTEREN, FOX NEWS HOST: Everybody knows who they are, but now you will know them a little better.
Earlier, the Backstreet Boys’ Nick Carter and A.J. McLean went "On the Record." They just released their sixth album "Unbreakable."
VAN SUSTEREN: Everybody wants to be you. Everybody loves your music. But people must wonder, you go out on stage and you think, "Not tonight."
A.J. MCLEAN, BACKSTREET BOYS: You have nights here and there where it could be something personal that you are going through that day, or you are just not feeling like doing a show that night, and you just kind of grind through it.
But even if any of us are having a really bad or stressed out day, the minute you hit the stage, you dump that off.
VAN SUSTEREN: What is the best concert you've ever done? What's the most fun for you, which ones?
NICK CARTER, BACKSTREET BOYS: We have had concerts in the past that have been phenomenal, like playing the Tokyo Dome two or three nights in a row. We have been fortunate enough to go all over the world.
Just recently we finally went over to Russia. And we played some gigs over in Moscow and then St. Petersburg, and that was amazing, because we got a chance to walk around the Red Square, and all sorts of things.
VAN SUSTEREN: Can you guys walk anywhere without being mobbed?
MCLEAN: If you really want to do it, you can, whether you wear a mask. I just bought a mask yesterday.
VAN SUSTEREN: It is his face, right?
MCLEAN: Yes. I bought a Nick Carter mask.
And it just depends. For me, personally, it is a little hard, because If I wear long sleeves or a turtleneck, my hands are tatted. I could shave my whole face, and fan still know.

VAN SUSTEREN: So, 15 years on top is a really long time in this business. It's a very fickle business.
CARTER: Especially for the type of music that we do. Groups have a very short shelf life, usually. We have been just fortunate enough to have the most amazing fans all over the world that have been so loyal and have grown up with us since we were kids.
And now they have kids of their own, so they are bringing their kids to the show and starting a whole new generation of Backstreet Boys fans. We are still seeing generation gaps between five and 85 in our shows, even now.
VAN SUSTEREN: Still, 15 years is a really long time. What is the secret? What do you think it is?
CARTER: The secret to us, I think, is a chemistry that kind of just clicks between five -- now four people. It is not usual, it's not something that happens often.
But I think we understand each other. We can relate to each other really well. Obviously we know the buttons that we can push with each other, because we have done that in the past. We don't really do that anymore.
And it's knowing each other. It's like a marriage between four people.
VAN SUSTEREN: What sports do you like, Nick?
MCLEAN: I am a diehard football fan.
VAN SUSTEREN: Which team?
MCLEAN: Tampa Bay Bucs.
VAN SUSTEREN: Did you want Brett Favre?
MCLEAN: I have a lot of respect for Brett Favre. I just got a jersey signed by him, so I'm very happy about that. I got that about two weeks ago. Thanks, Brett.
VAN SUSTEREN: People come to concerts and oftentimes want to hear the old stuff, and artists sometimes want to play the new stuff. Do you mind playing the old stuff?
CARTER: We love playing the old stuff. We feel that it is very important, because we are fans as well, like you said. So if we went to a Boyz II Men concert, or we went a Prince concert, we want to hear "Raspberry Beret," or we want to hear "I'll make love to you."
So we understand, and I think that is why our fans love us so much and appreciate us, because we understand what it is like to be a fan. So we give them what they want.
VAN SUSTEREN: Do you ever think 100 million albums we sold--100 million? Do you know how many that is? That's a lot.
CARTER: It is a lot of albums.
MCLEAN: It is a lot.
CARTER: We are so fortunate and so grateful for that. But at the same time I feel that--we feel as a group that we have so much more to achieve and so much more that we want to do. Selling records is one thing, and that's amazing that there are so many people out there that bought our records.
But I think we are in a rebuilding stage at this point. We just lost Kevin. He is still around. He's still around, but we lost him. But it is the kind of rebirth of this group.
VAN SUSTEREN: What is the weirdest music that you listen to, weirdest in the sense that fans would be stunned to think that you have this music?
MCLEAN: For me, I think probably it would be driving around back home in L.A. cranking Enya. I crank Enya. You will look at my truck and look at me with my tattoos and think I am listening to Korn or Slipknot. I love Enya.
In fact, I would love for us or me, or any of us to do a duet with her. I think it would be so much. She did it with Puffy, so why not do it with us? I love Enya.
VAN SUSTEREN: Ozzy Osbourne told me he listens to Frank Sinatra.
MCLEAN: That doesn't surprise me one bit.
VAN SUSTEREN: How about you, Nick?
CARTER: What would shock people that I listen to?
MCLEAN: I don't think there is anything to be honest with you.
CARTER: I am strange when it comes to music. I love country music. People would be shocked to know that I listen to Charlie Daniels band. I am a freak for Charlie Daniels band.
VAN SUSTEREN: Why?
CARTER: My dad used to listen to him all of the time. I pretty much know all of his greatest hits. We would always take camping trips, and that would be the CD my dad would always play, Charlie Daniels Greatest Hits.
