When I last posted about free opera in the Park, I urged you to go because it was the last performance this summer by the Met. But little did I realize (as you probably did, you opera aficionado you,) that the New York Grand Opera would be performing only a few weeks later. Tonight they are presenting a fully-staged production of Giacomo Puccini's La Bohème in the East Meadow at 7:30 PM. No tickets required. It's free. Enter at Fifth Ave @ 97th Street.
