Disneyland's opening is broadcast as a live, 90-minute TV broadcast to an estimated audience of 90 million. VIP guests include Frank Sinatra and Sammy Davis Jr., and Ronald Reagan is one of the showï¿½s hosts. Mickey is on the scene, cheerful grin firmly affixed. October 1955: The Mickey Mouse Club and the Mouseketeers debut on TV. The daily afternoon program is a smash hit with kids, and the annoyingly catchy theme song "(M- I-C! K-E-Y! M-O-U-S-E!") will be forever stuck in the head of anyone who hears it. Not necessarily in a good way. Annette Funicello is the most popular of the cast, and at her peak receives 6,000 fan letters a month. Mouseketeer caps soon become the rage, reportedly selling at a rate of 24,000 a day. November 1955: On Thanksgiving Day, the Mickey Mouse Club Circus, a 75-minute extravaganza of strangeness, opens as the first major addition to Disneyland. Within a pink-and-white striped circus tent, Mousketeer kids from the TV show perform aerial feats (!) and act in comedy routines alongside clowns, chimps, a troop of elephants dyed a rainbow of colors, a horse that dances unsteadily on its hind legs, and heavily tranquilized lions, leopards, pumas and panthers. This theater of cruelty features Funicello and fellow Mouseketeer Lonnie Burr in a cage wearing "Pussy Cat Polka" cat suits, and for the showï¿½s finale the Mousketeers appear in toy soldier outfits for the March of the Toys. The show is a huge flop, and closes in January 1956. Half a century later, every single thing that ever happened in that tent would be illegal.
