UPDATE 5.12.09 5:46pm: Our Rhett Miller sneak-peek listening party has been reset for this Thursday 5/14 at 10pm ET, 9pm CT, right after Rhett's guest shot on 30 Rock. Just point your browsers here.
BTW, I reckon the whole show will run 70 minutes or so, and a high-speed internet connection will be helpful, as will QuickTime (for the video interviews). But if you've got iTunes, you've got QuickTime, so don't sweat it. It's a good time either way. The wait'll be worth it, so we'll see you there! - frank
4.14.20092:16 PM: According to his twitter feed (@rhettmiller), Rhett will appear on the season finale of 30 Rock, playing himself. The episode is already in the can. No other details as of yet, though he's hinted that he may "live tweet" the show when it debuts. Set the DVRs, folks.
