Live chat during the Olympics Opening Ceremony U.S. telecast

It's time for the 2012 London Olympics to begin, and here at Yahoo! Sports we're gathering around the virtual fire to welcome in the Opening Ceremony. We'll be following the taped broadcast starting at 7:30pm Eastern. Your host will be Jay Busbee, joined by many of Yahoo! Sports' Olympic experts from Fourth Place Medal, and of course, you, dear reader. We've seen some of the footage live, and you're in for a treat.

Of course, you're welcome to contribute to the festivities. We won't be able to get every comment in, so be patient and persistent (being witty, informative and/or perceptive helps, too). Let's get our Olympics on!
