Courtesy of CthulhuWho1: An audio recording of the 1978 IguanaCon panel that attempted to answer the question "What if Lovecraft had lived till the 1960s?" Guests include Mr. Leiber, Dirk Mosig, J. Vernon Shea and a young S. T. Joshi. Get it here. The sound quality is surprisingly good.
(Fritz brings up the exchange with Lovecraft concerning the works of Charles Fort! Brain... might... explode...)
