If I were in New York on Sunday, I'd probably brave the crush and attend "Broadway on Broadway," a free concert being performed in Times Square starting at 11:30 AM. Almost every musical playing on Broadway (and a few about to open) sends over a couple of performers to do a number from their show, and they're sometimes quite wonderful. Here's a list of the tentative line-up.
All of the announcements say that the concert will be taped and chopped down to an hour for broadcast on NBC4 New York on Tuesday, September 9 at 7:00 PM. This should mean that thanks to my satellite dish, I'll be able to pick it up. But so far, no one has told TiVo about this event. It still thinks Extra is airing at that time, followed by Access Hollywood. I may have to settle for watching (but not hearing) via this link to a webcam that's pointed at the stage.
