Adam Arriving at Late Show

There’s a few more here. Reports say that once the band set up there wasn’t much room so he just stood there and sang his face off LOL. And that it was freezing (I know Letterman likes it cold in there for some reason)!
Here’s some random articles about Adam on the AMAs:
Eonline one here.
Funny Chicago Tribune one here.
