1982 Round Table Discussion with Isaac Asimov, Gene Wolfe, and Harlan Ellison
A half-hour syndicated talk program, covering the nature and marketing of science-fiction (or speculative-fiction) works. The hosts are named Studs Terkel and Calvin Trillin (which are not, in fact, porn pseudonyms).
A bit of interesting background to the interview can be found in the archives of Harlan Ellison's website. (Check the post for November 1, 2008 11:13:15)
