Philip K. Dick - Speaking His Mind ( ¿1977 / 1980? )

Someone has uploaded this in two parts but the other two parts aren't up anywhere. Here it is in full. Someone in a comment of the other upload claims this interview took place in 1977 for a book including interviews with science fiction authors called "Science Fiction: An Oral History." I'd have to track down a copy to confirm this and if I do I'll update. No copyright infringement intended ! ! !
