Many readers will have seen the transcript of a conversation between Lewis, Kingsley Amis, and Brian Aldiss on the topic of science fiction. It was first published in book form in Of Other Worlds, I believe. It's in the newish collection edited by Poe, C. S. Lewis Remembered, and in the book On Stories.
My question: Does anyone know what happened to the tape? Did it stay with the editor of the British science fiction magazine where it was first published? As things are, I don't know what happened to the tape nor who made the transcript from it.
If it is extant, it would be nice if it could be released on the Internet or sold as a CD or something.
