The Broadway star Sherie Rene Scott used to be a vegetarian—for 26 years, no less! But all things must end, and Ms. Scott is on a new kick, celebrating the bloody portion of her omnivore diet with Piece of Meat, a cabaret act at 54 Below, during which she sings Paul McCartney tunes—but don’t let him find out she’s offering them up as paeans to proteins! ... Meanwhile, those Collegiate Chorale crooners from Wednesday night are celebrating the 50th birthday of the American Symphony Orchestra at Carnegie Hall. And they thought they were rid of us old-timers!
