There was a stream. They were trying to get audio from four people in three different locations and had a lot of trouble. The stream was restarted several times. It looks like Twitch only kept the last two, which were as short as you saw. They said they were recording it locally and would try to get up on You Tube "soon", so maybe tomorrow.
Edit: I checked Twitch some more and found the rest of the stream in two more parts. Click on Videos at the top of the screen. The first four listed are the four parts of the stream. Start with the fourth one, the one that is 49:21, then go to the one that is 1:22:02.
