Most of the flower-power generation has mellowed by this point, even the musicians. Not Neil Young. The antagonistic son of a famed sportswriter still displays the same fire that fueled topical anti-establishment classics like "Ohio" and "Campaigner." Young displayed his latest one-finger salute to the man (and to a good chunk of his fanbase) on a 2006 jaunt with old cohorts David Crosby, Stephen Stills and Graham Nash. Billed as the "Freedom of Speech Tour," it found CSNY performing songs like "What Are Their Names?," "Military Madness" and "Let's Impeach the President" off Young's recent solo album, Living With War, rather than re-creating their quintessential live album, 4 Way Street. As should be expected by attendees paying top dollar for hits — not politicking — reactions were severe. In Atlanta, a third of the crowd reportedly walked out. This seems to have tickled the 62-year-old Canadian rocker/provocateur, who was documenting the tour for CSNY: Déjà Vu. The concert doc — which is presented at Beach Theatre as a fundraiser for WMNF — focuses more on fan than performance footage. The flick features an "embedded" journalist recording the concertgoers' reactions to the seeming bait-and-switch tactic that found them paying for a setlist rife with newly penned antiwar songs with only a relative few oldies ("Wooden Ships," "Teach Your Children") thrown in to minimize the sting. Did the rich rock star behave like a commendable rebel or a have-his-cake-and-eat-it-too lout? You decide. Fri., Aug. 1, 7 and 9:15 p.m., 315 Corey Avenue, St. Pete Beach, $8, 727-360-6697, beachtheatre.com.
