In the video, the held chord is an A, the dominant of the key of D, and the piano notes are

B-D-C#-A-G-B-A-F#-G-D-C#-F#-G etc (these may not be exact sequence, I'm in a hurry here, but the note choices are indeed what he's playin'...)

Man, that's an A13

Okay, to a rocker, its a Bm|A or maybe a Bm|A7 even though the 7 is on the piano and not the guit.

I don't hear any Bb in the run at all.
