Bobby Campbell sent me this link, commenting, "I found a video you might particularly enjoy."
Indeed, I did (although in fact I downloaded the handy MP3 file, so that I could listen to it during my commute). It's a video of Walter Block (author of the libertarian classic, Defending the Undefendable), Robert Anton Wilson and Dr. Demento, in a panel discussion on "Sex, Drugs and Rock and Roll" at the Libertarian Party's 1987 national convention in Seattle. Each panelist speaks for about 20 minutes (in the order I listed them,) then they took questions. Lasts about half an hour.
I did not know that Dr. Demento is (or at least was) a libertarian; his show is no longer nationally syndicated but is still available here. Dr. Block's book is available as a (legal) PDF download here.
