Is Keith Richards going soft in his autumnal years? According to Rolling Stone magazine, the guitarist has apologized to his band mate Mick Jagger for criticizing him in Richards’ bestselling 2011 autobiography Life.

The rare mea culpa appears in a forthcoming documentary about the band’s now half century-long career. “It was my story and it was very raw, as I meant it to be,” Richards says in the film, “but I know that some parts of it and some of the publicity really offended Mick and I regret that.”

Richards was certainly very critical at times of Jagger in Life, which he cowrote with White Mischief author James Fox. Chapter Twelve, for example, opens with with assertion that, “It was the beginning of the ’80s when Mick started to become unbearable. That’s when he became Brenda [Richards’ derisive pet name for the singer], or Her Majesty, or just Madam.”

Richards goes on to say, “This situation was a culmination of things that had been going on for several years. The immediate problem was that Mick had developed an overriding desire to control everything. As far as he was concerned, it was Mick Jagger and them. That was the attitude that we all got….Oh dear me, after all these years, the swollen head’s arrived. He’d gotten to where it wouldn’t fir through the doorway. The band, including myself, were now basically hirelings. That had always been his attitude to everyone else, but never to the band. When it dripped over onto us, that was it.”
