The youtube user known as Aronra made a pithy attempt to record Matt Dillahunty's appearance at the Texas Free Thought Convention, in Houston on 8 October 2011.
This is what he managed to record.
As it was recorded by Mr Ra the audio is aweful!
Please don't give us grief for Mr Ra's incompetence!
(If anyone seriously takes this as a criticism of aronra then all I can say is "Get a life!")
