That song probably means more to us now than when it was No. 1, just because of the way it makes us feel and makes the fans feel when we perform it live. As soon as it starts, everyone screams. At the end, when everyone’s belting the chorus out, it’s the best moment of the show. The common thing we get asked about that song is, “How sick are you of singing that song?” It means so much to us, 17 years into this career – basically that song has kept us relevant. I get emotional about it, honestly. Standing there [onstage], you hear [fans] screaming it back, I’m looking at my boys and I’m like, “We’re almost 40 and we’re still doing this” [Laughs]. And they’re louder now than they were back then."

Absolutely, when we first heard it. Clive [Davis] was still trying to get to know us and where our sound was, at the same time what he thought we’d be successful doing, and he brought “Liquid Dreams” and “All or Nothing” to the table right away. And “Liquid Dreams,” we weren’t sure if we were on the same page together with him. And then he plays “All or Nothing,” and I think all of us were happy to get the chance to sing that song. We knew that that was going to be our song. And we heard it with just the piano and a vocal. After it was over, we all just kind of looked at each other and we were like, “We’re gonna get to sing this?”

There’s certain songs that writers, like Adele, just say something so perfectly, and you’re like, “How come I couldn’t say that? It’s a simple line.” And that is what that song is, to say, “I want it all or nothing.” I think we’ve all said that in a relationship, or had that same feeling. And when somebody writes the song, you’re like, “How have we not written that before? How has it not been a song before?” To us, at least, it was an instant classic because it worded everything so perfectly – the music matched the emotion. What’s funny is that some people just listen to “All or Nothing,” just the [chorus], and we have people coming up saying it’s their wedding song and we’re like, “You know it’s about a breakup, right?” I also think that it’s a moment, because it was the last big boy band song of that era. And it sort of encapsulated the time period, because shortly after that, people don’t even talk on the phone anymore. So the line “One simple telephone call, you leave me here with nothing at all,” that’s not even necessarily the case anymore – there are so many other ways. And even beyond all that, it has an awesome key change. When key changes were still used! It did everything a key change is supposed to do. It’s the song that you cannot sing unless you double fist, close your eyes, pull your elbows down, stick your chin up in the air – that’s what the song does, even for us."
