New Kids on the Block stopped by The Late Late Show With James Corden on Monday night, and their sexy performance of "One More Night" surely brought more than a few Blockheads out of retirement. Although Mark Wahlberg sadly didn't join them on stage, their appearance was full of nostalgic nods to their glory days: subtle choreography, perfectly blended harmonies, and a standout moment from Jordan Knight (duh). Backstreet Boys might be ruling the Las Vegas residency game at the moment, but maybe NKOTB should be next?
