Mick Jagger made a topical David Petraeus joke when he introduced HBO’s new doc “The Rolling Stones: Crossfire Hurricane” at the Ziegfeld Theatre last night. “There’s a lot of change in America since we first came here,” quipped Jagger, who appeared with his bandmates. “This film . . . takes you back to a younger, perhaps gentler, America. An America where only IBM and the military had computers. Where there [were] no smart phones . . . no e-mails. And a simpler America, where we didn’t read other people’s e-mails, so we didn’t know four-star generals were having affairs.” And Jagger’s guitarist Ronnie Wood told us, “The main thing is the music we’re making now is the good [bleep].”
