Ok, so the Rockettes are not actually 75, but Radio City Music Hall is. On this day in 1932, Radio City Music Hall opened its doors to the public for the first time. Since then, millions of people have viewed the venue's famous Christmas Spectacular in Rockefeller Center. The kick line of talented women that dazzled viewers in the 1930s still entertains today - 5 times a day, 7 days a week during the Christmas season, to be exact. If that's not enough for you, promotional radios or mp3 players can keep the musical spirit going all throughout the year. Or you can check out one of it's other shows, which showcases famous names like Aretha Franklin and Dolly Parton.
