Australian children's-music sensations The Wiggles have been entertaining kids with wacky singing, silly dancing, and onstage antics for 20 years. The color-coded quartet uses songs, games, and storytelling to encourage participation from pintsize audience members, fostering a sense of youthful empowerment usually found only in preteen monarchs and omnipotent Star Children. Kids and parents alike are transported to The Wiggles' magical world of Big Red Cars, feather-wielding pirates, and rose-eating dinosaurs, licensing audience members of all ages to be silly and have fun. Concertgoers experience the show safely sequestered in the orchestra level of the NYCB Theatre at Westbury, enjoying a non-naked mole rat's view of onstage frolics and access to smile-feeding aural nourishment.
