yeah the setlist says "scayne" where the tech is noting the tunings...and long buried  on the gpn FB page is pics/comments from someone (possibly team flatline?) where they r commenting on pics from the earthday show in nyc "theres a pic of scott playing a flatline!" he was super pumped up whoever it was.

and i knew the V was in open E on paris...but cool 2 see grace plays in several different tunings, and with the cappo and all...stevie nicks and lindsay buckingham all in one! no shit.
