Many fans had waited in line for days to see the K-pop superstar perform. Some were able to see the megastar record the songs for broadcast.
"My sister was here since Monday and I just got here on Wednesday," a woman in line had said.
One family said they traveled all the way from Mexico to see the concert.
"Good Morning America" said the star pre-recorded three songs just before the weather rolled in, so that would air instead.
His performance coincides with the release of his first official global solo debut single "Seven."
Tune in to Channel 7 starting at 7 a.m. on Friday, July 14 to watch Jung Kook perform on "Good Morning America."
