International Poetry Incarnation
Shortly after his arrival, he gave a reading at Better Books, which was described by Jeff Nuttall as "the first healing wind on a very parched collective mind". Tom McGrath wrote "This could well turn out to have been a very significant moment in the history of England - or at least in the history of English Poetry".
The event 
The event attracted an audience of 7,000 people to readings and live and tape performances by a wide variety of figures, including Adrian Mitchell, Alexander Trocchi, Allen Ginsberg, Harry Fainlight, Anselm Hollo, Christopher Logue, George Macbeth, Gregory Corso, Lawrence Ferlinghetti, Michael Horovitz, Simon Vinkenoog, Spike Hawkins, Tom McGrath, Ernst Jandl, and William S. Burroughs.
The event was formative for what became the UK underground over the subsequent years. Jeff Nuttall, author of Bomb Culture said "the Underground was suddenly there on the surface". Barry Miles described "a sense of constituency that was never there before... All these people recognised each other and they all realised they were part of the same scene".
Coverage in other media 
Horovitz's related anthology Children of Albion: Poetry of the Underground in Britain was published by Penguin in 1969.
