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!

Jimmy Fallon and the roots also covered Camilla Cabello's 'Havana' with her earlier this year - check out that performance here:
