Here they are, recordings of the entire A&E show have been posted to YouTube.
You ask, what am I talking about? The Lexicon’s Supreme Mugwump Steve Vander Ark was interviewed by the Arts and Entertainment Network along with John Granger (Who Killed Albus Dumbledore?, Looking for God in Harry Potter) and Janet Batchler (What Will Harry Do?) for a show that explores the plot and mysteries of the Potter stories. Fun stuff, I promise.
