#BTSonFallon Trends As BTS Rides the Subway and Performs 'On' for the First Time on 'The Tonight Show With Jimmy Fallon'

BTS appeared in a special episode of The Tonight Show with Jimmy Fallon on Monday. The show saw the band ride the subway, serve sandwiches at Katz's Delicatessen and performed new single "On" at Grand Central Terminal.

The group sat down with Fallon in an empty subway carriage to talk about everything from the meaning behind their latest album Map of the Soul:7 and their whirlwind rise to international fame to what they aspired to be before they were BTS.

The number seven, featured in latest album Map of the Soul: 7, is a significant digit for the band. "Seven is a lucky number for us. There's seven of us [BTS] and we've been together for seven years. So we wanted to use that number for the album," RM explains.

"We've [BTS] been having a reboot," RM adds. The title of their latest single "On" is the reverse spelling of one of their earliest singles from their debut year 2013, titled "N.O.," and represents this rebooting of their mindset.

"We admit our shadows and honors at the same time. So [the song] 'On' is also for bring it on, and bring the pain," RM adds.

Reflecting on their journey from humble beginnings, from performing for an audience of 300 at their debut showcase in South Korea to global status, RM said: "We came from a small label in a small country in Asia and we proved that someone from the outside can be in the mainstream."

Jungkook added: "Everything happened so fast, It was overwhelming...I cried."

When asked what it was like to have fans in America respond to their music, Suga said: "The days never cease to amaze me."

J-Hope added that it is such "an honor" to have international fans, who come from a different culture, enjoy and follow their music.

Mid-interview, Fallon and BTS also broke into an impromptu session of George Michael's "Careless Whisper" when BTS member V said he'd wanted to be a saxophone player before joining BTS.

Other pre-BTS aspirations among the group included being an actor (Jin), tennis player (J-Hope), a pro-video game player (Jungkook), song producer/writer (Suga) and a businessman (RM), while Jimin joked he would have wanted his own television show, calling it The Jimin Fallon Show.

The group also answered some fan questions including "Which comes first when making music, the lyrics or the track?," to which they collectively said: "Definitely the track," explaining that, usually, the song comes to them first, from either a beat or melody.

And who have BTS yet to meet and would love to perform for? That would be none other than John Cena, who is a fan of the band, RM noted.

Fallon and the group also played a few rounds of the "Subway Olympics" during their train journey, which saw the host and BTS balance rubber ducks on one hand while trying to knock off the toys from each others grasps. They also did a dance battle wearing gloves to see who could shake off the gloves first purely by dancing furiously.

Later, the band dropped by Katz's Delicatessen, the city's legendary sandwich shop, and helped Fallon serve nosh to customers.

The show's finale was the group's first-ever live performance of their new single "On" within the historic enclosures of Grand Central Terminal.

BTS fans (collectively known as the Army) have been sharing their reactions to the band's appearance on the show, which was one of the most high-production episodes the show has ever released, using the hashtag #BTSonFallon. The term promptly top-trended on Twitter.
