It Usually Begins with Ayn Rand is a jazz improvisation on the early history of the modern libertarian movement, not a transcript. But what a sax solo! (Of course, Rand didn’t like jazz either.)
My own libertarianism had nothing to do with Ayn Rand, whom I did not read until late in life and only because I had to write an article. The key influences on me were Albert Jay Nock's Memoirs of a Superfluous Man and George Woodcock's Anarchism.
