Backstreet Boys and New Kids on the Block cash in with Canadian after-parties

Middle-aged pandemonium is anticipated in Toronto this week, as the Backstreet Boys and New Kids on the Block arrive with their joint tour, and show that boy band life doesn't end at 30. Let alone 40.

But with no new songs to sell, save for a couple of collaborative tracks on a combined greatest hits album, there might be more motivation to find new revenue streams.

Enter the hip-hop-inspired after-party, where members will turn up at a local club, with the promise of mingling with fans who haven't been fulfilled by the concert alone.

"Minimum two members of the band will be present," promised the advertisement for a late Tuesday appearance by the Backstreet Boys at Montreal's Light UltraClub. As the quartet was be fresh off the Bell Centre stage, the condition might have given two of them an excuse to go to bed earlier, if they wanted.

Such events are now routine, evidently, as yet another after-party is scheduled for Thursday at Tequila Jacks in Toronto. The promotion similarly states that "not all members may attend."

Still, at least some Backstreet Boys must appreciate their cut of the $20 advance ticket price, or $25 at the door.

But, for the more domesticated members of New Kids on the Block, the club circuit has seemingly held less appeal. The most notable exception would appear to be its hardest-partying member, Donnie Wahlberg.

Following the concert at the Air Canada Centre on Wednesday, the 41-year-old New Kid has invited fans to hang out with him at the C Lounge, where a $35 general admission is apparently enough to get anyone past the bouncers.

Wahlberg has also turned to his longtime bandmate for an upgrade. An extra $115 will provide access to a lounge presided over by NKOTB singer Jordan Knight.

For the most enterprising New Kid, though, there might be an added social incentive to make new friends around Toronto.

The most famous recent buyer of a high-end Yorkville condo turned out to be Donnie's younger brother, rapper-turned-actor Mark Wahlberg.

Presumably, his single sibling might also borrow it from time to time.
