As artdaily reports, Sotheby’s put those letters up for auction in 2012. They contain a wealth of insight into Jagger’s intellect and artistic drive at a tumultuous time, not only for the band, but for the world at large. Dr. Gabriel Heaton, book specialist at Sotheby’s, said the letters “afforded an insight into how one of the central actors in the momentous cultural events of the time saw the world as it changed around him.” They also contain priceless rock and roll memorabilia, as Jagger included the lyrics to “Monkey Man,” as well as a track list with personal notes written by the singer.

According to Rocks Off Magazine, Jagger got no satisfaction from mere correspondence. Hunt wrote in her 1986 memoir “Real Life” that the singer eventually showed up at her front door in London in the middle of the night. “Framed by the doorway as he stood grinning with a dark coat …,” she wrote, “He drew one hand out of his pocket and pointed it at me like a pistol … Bang.”

Their relationship lasted only nine months, but the two ended up having a child together, a daughter named Karis. However, although he liked Hunt enough to use her as inspiration for hit songs like “Brown Sugar,” he wasn’t in it enough to accept that Karis was his child. He neither wanted to pay child support nor admit that he was the father, but finally did so after nearly a decade in the courts.
