Watch the Backstreet Boys and Jimmy Fallon perform 'I Want It That Way' on classroom instruments

It's a classic that you would have heard countless times before, but Jimmy Fallon has spiced it up with children's instruments of all things.

The lack of expensive equipment is made up for in pure talent as they absolutely kill it! 

The white outfits are a cool addition as well, a nod to the original music video, but luckily there are fewer singlets and fedoras here!

They seem to have come quite a way from one of their first toy instrument performances with Adele back in 2015, watch that performance here:
