it was definitely a set highlight (it was in the bridge of angry johnny and the radio), brian had a couple of great jokes regarding bon iver afterwards (they weren't negavtive at all, respectful. - his banter w/ audience is on the level of a stand up comedian, in my opinion. As far as i could tell, no one was capturing video during it thought..
They apparently added the bon iver bridge in at the Bunburry set tonight in Cincy tonight as well.
also: someone in the dimestore saints boards posted a great recap of the stl show and it includes all of the little details in a great summarized format, i'd recommend checking that out.. because there were so many little things that made that show perfect.
