I have found videos of part of the American Revival seminar held by Glenn Beck on March 27th. This seminar was 6-7 hours in length and, as you can see, there is quite a bit of it in these videos. I'm sure you won't be able to devote the time needed to watch this in one sitting so I have added this post to the 'recommended videos' section on the right side of the home page.
The audio isn't the greatest but is understandable. Hope you enjoy.
