Back on September 28, to get fans hyped up for #BTSWEEK coming on 'The Tonight Show Starring Jimmy Fallon' all this week, NBC launched a massive sing-a-long on Twitter!
First, the sing-a-long was started by NBC Entertainment's official account on September 29, as the broadcasting station launched into the signature opening line of BTS's "Dynamite". Soon, numerous NBC-affiliated programs jumped on for the epic sing-a-long. Literally, every single NBC program's official Twitter ever!
Check out the huge thread below:
