Yes, Jay Sebring was the hairdresser. It's said he was the only one who attempted to defend them.
Shows what a sad collection they were, because it shouldn't have been difficult to kick the shit out of Tex Watson.
Sebring was the one who helped launch Bruce Lee's movie-career as well.
Sebring and Tate
Tate went from Sebring to Polanski, but kept Sebring as a "Friend".
Bruce Lee taught martial arts to Polanski, who was so devoted he flew Lee to Gstaad, Switzerland to give him lessons.
“It’s fantastic when arrangements are made by him,” said Lee to Black Belt magazine publisher Mito Uyehara. “I go to the airport and a chauffeur is waiting for me with his limousine. He takes me to the finest hotel and the next day he comes back to take me to the airport for my connecting flight. I don’t spend a penny and I live in luxury. Everything is so well planned that I hardly go through any hassle.”
“I didn’t realize how the ultra rich spend their time, until I visited that resort spot in Switzerland. The rich have a boring life, too. Drinking and skiing is about all they do. In between, everyone is truing to take someone to bed. I was the only Asian there; all the others were Europeans.
“Some of the girls were about 14 or 15 years old, making passes at the old guys who were at least mid-50s. At first, I thought it was kind of strange but later I learned that morals do not exist there. No, those kids weren’t their daughters. They could have been whores, I guess. I really don’t know why those kids weren’t in school. It was a strange situation.’Lee also tried skiing.
“I was going 60 miles per hour down the hill and made it all the way down without falling. I didn’t feel any excitement in that sport, so I never tried it again.”
Lee also taught Tate martial arts for her role in The Wrecking Crew, and did fight choreography. The Wrecking Crew was a spy spoof starring Dean Martin, in the vein of Austin Powers. It was incidentally Chuck Norris’s screen debut.
