Yummy versus yoga! The James Beard Foundation, long promoting a unilateral foodie agenda, celebrates its 20th anniversary by hosting a food festival at—where else—Williams-Sonoma! Illustrious pillar of French cooking Daniel Boulud signs his cookbook and gives cooking demonstrations for a room full of hungry maniacs at Columbus Circle. Meanwhile, not far away, stringy yoga gals spread their sticky mats for Health magazine’s outdoor yoga festival in Central Park, featuring a performance by Joan Osborne—yes, she’s the one who sang “What If God Was One of Us.” Jewel must have been booked. Yoga teacher Sarah Ivanhoe will teach her “detox flow.” “There are a lot of different yoga postures we do to facilitate the cleansing of the body,” she explained. “It taps into the apana energy, which is a downward, outward force: The same force you use to go to the bathroom or give birth.” Better warn the Parks Department. Ms. Ivanhoe will be featured on VH1’s latest sickly brilliant entry into bottom-feeding, Celebrity Rehab (it was only a matter of time …). “I’m part of the rehab team,” she said. And in retail therapy news, A.C.E. (Association of Community Employment Programs for the Homeless) hosts a SoHo Stroll, featuring free stuff and discounts at various SoHo stores and the raffle of a red Vespa scooter, which, frankly, is the best reason we’ve heard lately to brave SoHo on a Saturday. Later, it’s a big night in music: Our idol Lucinda Williams plays the Fillmore, while a lot of stoned 30-something lonely girls sway to and fro reliving their lost youth, and Kaiser Chiefs—those catchy rockers responsible for the instant classic “Every Day I Love You Less and Less”—play the Beacon Theatre. Expect disheveled men in skinny jeans! (And you know what? They can have ’em!).
