From Boston with love, New Kids on the Block has launched a 42-date spring/summer tour of North America. Featuring opening acts TLC and Nelly, the entourage will appear Friday at the Smoothie King Center in New Orleans.

Upon announcing the tour in January at Madison Square Garden in New York City, the New Kids, all of whom are in their 40s, said that young boy bands of today who want to learn about the right stuff should study the New Kids in concert.

“As far as boy bands, we dance, we perform,” said New Kids member Joey McIntyre, 42. “I mean, I hate to sound like an old fogey, but these kids don’t know what they’re missing nowadays because we got to sing and dance for our supper, and we love to do that. “So maybe a few kids could come to the show and see how it’s done,” McIntyre added, possibly referring to One Direction, 5 Seconds of Summer and others.

During the tour announcement, Donnie Wahlberg, 45, cited the decades-long bond between New Kids on the Block and their fans.

“We keep it alive because it stays alive between us and our fans,” Wahlberg said. “It’s a real relationship now.”

New Kids Wahlberg, McIntyre, Danny Wood and brothers Jordan and Jonathan Knight began working together in 1984. They’ve sold more than 80 million albums. The group’s No. 1 albums include 1988’s “Hangin’ Tough” and 1990’s “Step By Step.” The hits released by New Kids on the Block include “You Got It (The Right Stuff),” “Hangin’ Tough,” “Cover Girl,” “Didn’t I (Blow Your Mind This Time),” “I’ll Be Loving You” and “Tonight.”

Dubbed The Main Event, the New Kids tour began May 1 in Las Vegas.
