BTS has begun a two-night stint on The Tonight Show Starring Jimmy Fallon, where they will sit down for an interview after recording a performance of "SWIM" at The Guggenheim. The audience also saw a pre-recorded segment showing fans entering a recording booth to sing "Swim," the lead single from BTS' sixth album ARIRANG.
