You need to follow Dart Adams on instagram/Twitter.
He's giving a ton of history on some of the detailed moments of the mini series.

There was one last night in EP2 that I KNOW has to be something.
When the guys were in the hallway before doing Soul Train,
somebody walked by and gave them a "what's up".
And they lingered on that moment longer than others which
made me think he was something important.

Anybody know who that was?
