At first glance, it's easy to mistake the Happy Together tour for that other annual oldies trek known as Hippie Fest. It boasts one of the same headliners in the Turtles, whose onstage antics under the aegis of their original frontmen Mark Volman and Howard Kaylan (AKA Flo and Eddie) always provide a reliably rousing stage show. With a classic catalog consisting of timeless delights "Eleanor," "You Baby," "She'd Rather Be With Me," and, of course, the tune providing the banner for this bonanza in the first place, their star billing remains well-deserved. But here's the difference — while the audience for the two tours may be practically the same, the Happy Together extravaganza recognizes that hippies and hipsters weren't the audience for the giddier radio fare that distinguished AM from FM back in the day. Consequently, there may be broader appeal for the Boomer brigades, given a supporting cast that includes Mickey Dolenz of Monkees fame, Rob Grill of the Grassroots, Mark Lindsay of Paul Revere and the Raiders, and the Buckinghams, whose biggest number, "Kind of a Drag," kind of makes them an also-ran in these leagues. Still, with a combined repertoire that includes "Last Train to Clarksville" (Dolenz), "Let's Live for Today" (Grassroots), "Kicks" (the Raiders) – in short, enough hits to sustain several seasons of Glee – count on the Happy Together tour to instill a merry mood all around.
