Is it going to be the entire St. Augustine performance? Or is it gonna be certain songs interlaced with footage from other shows or PBS panhandling? Also, has the time been announced?
I do wonder why they picked the St. Augustine show to be filmed for the special; Brian was still very nervous (not to mention auto-tuned) at the time. Even though it'll be an accurate representation of the May 4th gig I went to 2 days after, those two later Chicago shows would've made for a hell of a special. Either way, ya can't really go wrong with any of the dates from this tour from what I've heard/read.
The whole thing is apparently 56 minutes long. Considering they are apparently working in "making of" footage of the new album and some sort of "archival" footage, I'm guessing we'll get only a hand full of songs from the St. Augustine show.
As for why they picked that specific show to shoot, my only guess is that in order to edit the thing and have it aired in June or July, they had to pick an early show on the tour to do it, and pick a venue that could handle the video shoot. Then again, one article talked about scouting locations to shoot the live footage and one they considered was the Greek Theatre in Berkeley. Not sure how they would have shot the show and edited it into the special so quickly. I'm sure it could be done in days or weeks, I dunno.
