I just got back from this show and it was awesome to say the least...my first STP concert. As someone posted earlier, Scott butchered Down pretty badly, to the point where Robert said "this is the worst rendition of this song we've done." Scott forgot the words and eventually they stopped playing, picked up on Dean's solo, and then they finished it correctly. Scott started singing the first verse as soon as the song started, therefore he was ahead of the rest of the band.
Aside from that hiccup they were phenomenal and Scott sounded great, much better than I thought he sounded during the Kimmel performance. Looking forward to seeing them again in August!
