Apparently the person who interviewed Frid must have done so in the early '90s when Frid's opinion of DS was horrendous and Frid had done many interviews in which he said awful things about the show and how he wanted nothing to do with it ever again. But then, that was also the period when Frid and Pierson had had a colossal falling out over Pierson using footage on an MPI VHS of one of Frid's one man shows without permission. To say Frid was livid would be an understatement...
Thanks for the link, Gothick!
