He's known to millions, in the words of Arthur C. Clarke, as “The most famous unknown actor in the world.” Richter was a mime (and a poet) during the 1960s, but also gained cinematic immortality as "Moonwatcher" in the iconic "Dawn of Man" sequence in Stanley Kubrick's 2001: A Space Odyssey. This in itself would be enough to stir our interest, but Dan was also intimately involved with John and Yoko as a personal assistant for five years, during which time he helped manage their film and recording projects while kicking his heroin habit. He tells his story in compelling detail in his book, The Dream is Over: London in the 60's, Heroin and John and Yoko.  Joining the conversation is guest co-host Ian McNabb (see SATB 234). The conversation covers Dan's time with the Lennons, as well as work on 2001 with Stanley Kubrick.
