Each night, 60,000 fans came to the stadium to watch the seven-member boy group perform on their Speak Yourself world tour. The concerts were not only seen by those in the venue, but also broadcast in livestreams to the world on V Live.
On the second night, Big Hit arranged a special moment for BTS, unbeknownst to the group. Before the show, they announced to the audience that a moment would come up where the screens would black-out before displaying the lyrics for "Young Forever", at which point fans were asked to sing along and surprise the members.
Of course, ARMY don't do anything by halves, and when the moment came, they sung "Young Forever" with full force while the boys watched in awe. They all had tears in their eyes, while Jungkook and Jimin were visibly overwhelmed and began crying.
