SPAMMMERS alert.
Chris, yeah that had a couple I knew in it and one I didn't. Mostly in that one he's playing around with the dominant 7th to 6th thing, and playing minor to major 3rd which is very rockabilly. I can do it in E, but doing it with barre chords is way hard on the index finger. I can do it, but not cleanly. Still get buzzes and dull/dead notes. Got to polish a piece and post a vid one day.
Thankfully some people on the internets have been forthcoming with some great information. I'm sure now that one chord he walks around is a 13th, and another is a first inversion chord.....
Here's a video a great player posted for me as a video response to a question! I saw him playing the same chords and asked him about them. What a great guy (and player too!)

But actually someone sent me the tab, and I can't tell you how grateful I feel right now.
