Goo Goo Dolls kick off a summer tour tonight in support of their current album Boxes. Because the Goos have been around since 1986, multiple generations come out to see them live. That's something lead singer Johnny Rzeznik never expected, but he finds it "gratifying."

"I’m surprised when young people come out to see us," he tells ABC Radio. "And it’s sort of interesting, because when I was a kid, there was no way I was gonna listen to my father’s records! And now kids love listening to their parents’ music. It’s become an experience that they all share together, so it’s great."

"I wish I could’ve had that kind of bond with my parents," he laughs. "But I wasn’t about to listen to Lawrence Welk records!"

In addition to the string of hits the band has to play every night, Johnny says they're "definitely" going to do material from Boxes.  They're also planning to "throw in a couple of surprises," says Johnny, explaining, "It’s time to do something different."

Goo Goo Dolls have a few shows scheduled in North Carolina next month, but unlike some acts this summer, bass player Robby Takac says he doesn't think that they'll cancel them in protest over that state's controversial "bathroom bill," which some say discriminates against the LGBT community.

"You know...there’s Goo Goo Dolls fans there," Robby tells ABC Radio. "And not all those Goo Goo Dolls fans have the same unpopular opinion that their government has. So, to me, I’m torn, quite honestly...Because there’s great people there, too."

"It bums me out that those people are gonna have to suffer," he adds. "But I guess you gotta make that decision at some point."

Goo Goo Dolls are on the road through September in the U.S In October, they'll tour the U.K.
