For a time the Manson family lived on Sunset Boulevard with Dennis Wilson of the Beach Boys who was initially impressed with Manson's songwriting skills. They also took enormous quantities of LSD. Later, in 1969, members of the Manson Family broke into the home of Roman Polanski and brutally killed Polanski’s eight months pregnant young wife Sharon Tate and several others in what later became known as the Tate-Bianca murders.
Director Roman Polanski’s film Chinatown (1973) starred Jack Nicholson, in whose home the 1977 event which led to Polanski's arrest and subsequent flight from the country took place.
Marlon Brando at one time lived next door to Jack Nicholson. Sometimes Brando would walk over to Nicholson’s house for milk and if Jack was not home, Brando would leave his underwear in the fridge where the milk had been.
In the spring of 1973 during a Beach Boys concert at Ohio University I walked to the front and handed one of the band members a drawing which I had made in pen in ink, tearing it from my sketch book while standing next to the stage. He seemed to like the drawing and thanked me for it.
Conclusion: Based on the theory of six degrees of separation, anyone who knows me is within six degrees of Jack Nicholson, Roman Polanski, the Beach Boys, Marlon Brando and Charles Manson.
Think about it.
