So after playing and doing a little more dissecting of the teaser, Rogers isn't playing what's in that Reddit tab. You can see him move from the B(7th fret E string) to the D(5th fret A string). And then on to the F# and E. It seems like Rogers is playing a more Rhythm part and then the more funky part is a 2nd guitar. There also seems to be some sort of 80's pop key stuff that just going to the chord progression. Then the bass line and then a normal piano that makes up the backing chord progression. Also, the first SNL ad sounds a little different than what we hear in the teaser.
