The link above only seems to give the video of the president's opening speech, just over 4 mins long.

I watched the concert via the PBS stream (was on from just past 1 am to 2.15 am here in UK) with the FB chat although there were only about 7 people on that general talk link. Joan Baez & Bob Dylan only sang one song each and didn't duo or come back on stage for the final song from what I could see. Dylan looked a bit uncomfortable at the end of his song & I guess as the concert was pulled forward by a day there hadn't been much rehearsal/sound checking time. Morgan Freeman was relaxed as the main MC. @joanbaez had tweeted when she was on her way to Washington.

I can't find the full concert up online yet, maybe PBS will be putting it up online after editing the between songs stage rearranging breaks.
