We're exploring lost territory today with Jim and his guest, filmmaker Matthew Serrano. Matt's new feature documentary, "Live from the Space Stage: A HALYX Story," reveals the history behind the Tomorrowland rock phenomenon that only appeared in Disneyland during the summer of 1981. You can see the movie now on Defunctland on YouTube.
