I heard recently that a friend of a friend, owner of a cassette recording of Allen Ginsberg reading from 1964, had converted the recording and uploaded it to YouTube. The recording is below, cut into four sections. It was recorded at Better Books in London. Included are the following poems, along with some fascinating/humorous commentary from Ginsberg.
