Dylan Thomas and a cast of actors gave this classic performance of one of the greatest of radio dramas.
Update: Sorry, forgot the last part.
Update 2: Ah, no, it's called, by Thomas, "A Play for Voices" and it was commissioned by the BBC as a radio play. This production was done live in New York, the poet reading the "First Voice" part which he, having died, was first performed on radio by Richard Burton. Other parts were played by other actors, including Sada Thompson, Nancy Wickwire, Allen Collins, Dion Allen, Roy Poole, playing multiple roles. I don't think the later recording that was read by just Richard Burton is nearly as effective.
It was a radio script which BBC producer Douglas Cleverdon had been coaxing for years from Thomas and which was finally delivered in October 1953, a month before the writer's death.
