The "Radio City Christmas Spectacular" is a beloved Christmas musical stage show that's been running since 1933 at the Radio City Music Hall in New York City. The show has become an iconic holiday tradition, featuring everything from dancing to singing, live music, and even an appearance from Santa himself. The show has been running every year, except for a few gaps during World War II and the COVID-19 pandemic, so it's been going strong for almost 90 years now!
