The New Kids on the Block have a brand-new music video that just hit online. Not only is "Boys in the Band" a new song with a new video, but it is a love letter to boy bands -- past, present and future.

The "Boys in the Band" video kicks off with a teacher who teaches a history class about boy bands inviting that day's special guests, New Kids on the Block. At that time, the door opens and NKOTB walks into the classroom as old men with walkers, looking very cranky.

Then, the music starts and they start to sing. The beginning of the video sees them doing very slow moves similar to their "Step by Step" music video. 

It is at this point that they relive some big moments in boy band history. It starts off with them morphing into a band dressed like The Jackson 5 and even has Donnie Wahlberg on guitar. Then it comes time for the '80s, and their clothing turns into New Edition, and they act out moves from the song "Mr. Telephone Man.". 

At this point, former New Edition members Ronnie DeVoe, Ricky Bell and Mike Bivins all come into the classroom and interrupt the video. When it moves to the next step, it is time for an NKOTB reference, with "The Right Stuff" dance moves and then some "Hangin' Tough" choreography.

Debbie Gibson also pops in as a sexy school teacher and sings the hook.

At this point, Donnie starts to rap and pays homage to other boy bands. Included here are Bell Biv DeVoe, Backstreet Boys, B2K, 98 Degrees, LFO, Menudo, JLS and today's biggest boy band, K-pop stars BTS. After mocking the "Bye Bye Bye" music video, Wahlberg then gives a shout out to One Direction. Finally, they wrap it up with a reference to Take That and a homage to "Back For Good."

For people who want to have their boy band education in person, New Kids on the Block are heading out on their The Mixtape Tour and have a huge show lined up in Las Vegas at the Mandalay Bay Events Center on May 25. AXS has tickets on sale now (Tickets).
