Sarah Lyall, in The New York Times, 3/4/08, reported:

“A plot by the Hells Angels, … in 1969, to kill Mr. Jagger nearly 40 years ago failed when the would-be assassins, traveling by boat, encountered a storm and were thrown overboard, according to a new BBC radio series. In one episode of the series, ‘The F.B.I. at 100,’ a former F.B.I. agent, Mark Young, said that Angels became enraged in the aftermath of the Rolling Stones free concert at Altamont. During the concert a fan was stabbed and killed by the Angels, who had been providing security for the Stones. The Stones then distanced themselves from the Angels, which made the Angels angry with Mr. Jagger, the program said. “They were going to kill him in retribution for his firing their security forces,” Mr. Young said in the program, the BBC reported on its Web site. “Their plan involved making entry into his Long Island property, going by boat. As they gathered the weaponry and their forces to go out on Long Island Sound, a storm rolled up, which nearly sunk the watercraft they were in, and they escaped with their own lives.” Mr. Young told the program that the botched plot came to life much later, in the course of a wider investigation into the Angels’ activities… A spokesman for Mr. Jagger said he would have no comment.”

We could have saved them a lot of trouble in uncovering this plot, if only they had done some research at the ARC first!

One of the many rock pulp paperbacks, this from 1977, at the ARC.
