“Look around this room,” exclaimed Youth America Grand Prix Board Member Terry Zucker, panning around the Promenade of the David H. Koch Theater, at YAGP’s “Stars of Today Meet the Stars of Tomorrow” Gala. In it mingled New York’s Junior social set, balletomanes, young dancers in tutus and established stars in gowns. The two hour performance preceding it was a sublime combination of classic, contemporary and Latin choreographies, ballet students beginning their professional trajectories and notable alums leading their way. “Bringing in the Olsen Twins has made it more fun,” continued Zucker. “It had a huge impact.” The change of chairs to Amy Astley, Marcella Guarino Hymowitz, Ashley Olsen, Mary Kate Olsen, Colby Mugrabi, Candice Miller and Lesley Thompson Vecsler brought a sea change of young pretty things. The Olsens, established designers of The Row, made certain the room was well presented. “They picked the music, changed the tables, designed the flowers (in pink Capezio ballet slippers). They brought more people in and made it younger.”
