Mexican Samba; Japanese style????

So today I went to Chou Elementary School for the first time. I didn't go last month b/c we had the typhoon warning and school was cancelled. Classes went well and the kids are so kawaii, the usual. In the afternoon though, I was asked to attend a combinded 4th grade class. The students were practicing for some sports thing and they incorporated an English number lesson into the practice. They wanted me to help with the counting aspect. So I show up in the gym and before the counting begins the teachers turn on the "samba" music. There were over 100 4th graders in the gym with shiny metallic pom poms in their hands. They start doing a choreographed dance to what sounds like the "Copa Cabana" song, but in Japanese. I start to giggle, b/c it's so damn cute and funny. The teachers are so proud b/c they created the routine and the kids are doing a great job. Fortunately I took my phone into the gym and was able to catch a few images. I wish I had my digital though, but I just didn't want to bring it to school today especially b/c it was so rainy. After their performance, I applauded loudly and the teachers kept asking me if I knew the samba. They even showed me a hysterical video with some Japanese guy dressed in a glittery kimono doing samba moves. I should own that video!
