We run around onstage constantly for about an hour and 45 minutes, and we know what that can do. You just feel great at the end of the night and when you wake up in the morning.

We write our own songs, play our own instruments.

We've played every dirty rock-and-roll club in America, and we've been opening acts for everyone.

It's awesome to play 1 1/2 -hour shows because it's so much fun, and we enjoy every single minute of it.

We are, you know, not perfect. We live every day day-by-day, and we do the best to make our mom proud.

We have Common on one song called 'Don't Charge Me With the Crime,' which is one of my favorite songs. It's a story song. It didn't really happen to us. But it's definitely fun to have him on the track.

You can feel how the audiences react. For us, it's about the performance and the reaction. We feed off the energy. And no matter how enthusiastic they are, we can tell if we're playing well or not.

There was one incident where we couldn't hear ourselves, so we were singing in an entirely different key than the instruments. It gets so loud at a Jonas Brothers concert!

We honestly cannot hear sometimes because the audiences are so loud.

Travis Barker is one of the greatest drummers ever, and all the guys in blink are really good songwriters.

We have the most amazing security team around us, and beyond that, our fans are just very enthusiastic, and they have a great way of showing their enthusiasm.

We really do get along, I think because we have a bit of respect for each other being in a band. But, of course, we're brothers.

Yes, there is another brother. His name is Frankie.

This music really is us. We're not, like, a manufactured version.

We got very lucky, and we were really honored with how amazing our family is now at Hollywood Records... They believed in us, and they let us make the record we definitely wanted to make. And they let us be the Jonas Brothers.

Each year when we set up a new tour, we kind of push ourselves to come up with new ideas and new exciting things.

Rumors are always out there.

We've grown up with the idea that even when you're at the top, act like you're at the bottom.

We wake up and pinch ourselves most days.

The online thing has been really big for us: the YouTube videos, the MySpace.

Moms are sometimes the craziest because they know they want to get their daughters to be seen by us or get an autograph.

The first record took us, like, a year and a half to make. The second one took 21 days, including weekends.

We were definitely new to the whole music thing. The first album was a real collaborative effort between us, the writers, and the A&R people at Columbia Records. We really worked to find out what our sound was.

We didn't tell anyone we had gotten signed, because people can freak out a little. But we started working with writers. I remember that I missed three to four days of school every single week, and people were, like, 'Where are you?', but I couldn't say anything, because we'd talked about keeping it to ourselves.
