One of Jimmy Fallon's more popular gimmicks on The Tonight Show is when he gets musicians to sit around and perform their hit songs using a classroom instrument. The most recent example of this came this week when Fallon had the Backstreet Boys and The Roots on his show to sing "I Want it That Way."
Similar to past versions of this gimmick, the bands used everything from a tambourine and kazoo to a ukulele, wood block and melodica. Past performances included Fleetwood Mac's "Don't Stop" and Ed Sheeran's "The Shape of You."
Later on the show, Backstreet Boys performed their live version of "Don't Go Breaking My Heart," a brand-new single released in 2018.
Of course, The Roots are Jimmy Fallon's house band on The Tonight Show, as well as four-time Grammy-winning R&B artists. As for the Backstreet Boys, the extremely popular '90s boy band has been touring the world over the past few years, releasing their most recent album in 2013 with In a World Like This.
"I Want it That Way" was the band's platinum-certified 1999 single from the album Millennium. That album was the band's first major hit in the United States, as well as their first to hit the Billboard 200 charts, where it peaked at No. 1. "I Want it That Way" was the lead-off single for that massively popular album.
