On the road (sort of) with Jonas Brothers

The Jonas Brothers have sold millions of albums, scored big with the recent Disney Channel movie "Camp Rock," and are now, oh, about as famous as Miley Cyrus was two weeks ago. In fact, the boy band's Hanson-like stars, ages 15 to 20, may have just surpassed her as the objects of your child's affection.

Now the Jonas Brothers are on a nationwide tour to support their album "A Little Bit Longer," which arrives Tuesday. But tired of giving sound bites and posing for quick photo shoots, they say they wanted to find a different way to expose themselves to their adoring, disposable-income-spending fans. So yesterday, when they made a stop in Boston hours before a performance at the Comcast Center, they invited a few members of the media to tag along.

When I got the invite, I picked out an outfit and texted everyone I knew. Here's a roundup of everything that happened from the time Nick, Joe, and Kevin started their day to the moment they left the city.

11:45 a.m. "The boys," as they're called by everyone on the tour, walk into a Ritz-Carlton conference room single file and sit at a table in front of microphones. They're all in skinny jeans (Kevin's pair is white). They smell nice.

Kevin brushes his bangs back every few minutes. Joe is mostly quiet and has perfect eyebrows. Nick says he's psyched that Rolling Stone recently compared the Jonas Brothers to Cheap Trick. "That was really cool for us," he says. Kevin says that maybe one day, he'll attend Berklee College of Music. John Taylor, the band's music director, is a former Berklee student.

"We stole him away," Kevin says. "That seems to happen to most Berklee kids."

12:30 p.m. The Jonas Brothers want to play tourist on their tour. So when we leave the Ritz, a Boston Duck Tours boat is waiting. The driver asks if there are any Yankees fans on the bus. All three Jonas Brothers raise their hands. (For shame!)

Once we're in the water, the driver allows the youngest Jonas - Frankie (he's been called the Bonus Jonas), to drive. At 7, Frankie already has his own band, Hollywood Shakeup. But oddly, when the driver asks Frankie what he wants to be when he grows up, he says he wants to invent things for the military.

Back on land we soon pass Government Center, and the Jonas Brothers point and scream. Here, they explain, they once played a New Year's Eve show in the freezing cold. "I thought I was going to die," one of them says.

3:30 p.m. We go to the Comcast Center in Mansfield and are treated to food from the catering company that feeds the Jonas Brothers every single day. Turns out the Jonases like chili, hot dogs (or tofu dogs), potato salad, and Fanta.

4:30 p.m. We're allowed to board the Verizon Mobile Recording Studio, where the band lays down tracks on the road. This bus, equipped with laptops, an electronic drum kit, and snacks, has been used by Timbaland, Linkin Park, and Madonna.

Erik Niewiarowski, the bus video engineer, says that of all of the Jonas Brothers, Nick spends the most time recording: "Nick's a workaholic." Traveling with the boys, Niewiarowski says, is "like the Beatles plus 20 because everyone has a cellphone."

5:30 p.m. The brothers have chosen the Boston stop on their tour to shoot a Burger King commercial. While they're being filmed backstage walking back and forth with a man dressed as the Burger King, Carolyn Weyforth, who planned this press outing, explains that before working for the Jonas Brothers, she coordinated press for Mitt Romney. The gigs are similar, she says.

7 p.m. It's time for a quick meet-and-greet with a few hundred fans who will have two seconds to get a picture with the boys. Despite the long day, the Jonases look fresh and clean. Kevin says "thank you" to every single girl. Then they're off to perform.

After the encore, they'll be on their way to New York for an appearance on "Good Morning America" and shows at Madison Square Garden. So they'll do what their crew calls a "quick out." That means they'll be off the stage and on the road before the still-screaming fans even know they're gone.
