Since 6 years I'm holding a big performance once a year with all classes and parents.  This year was by far the best performance ever.  

Please do have a look at my You Tube channel.  I put up lots of videos here, and on my Japanese Blog there is an edited one where I've tried to get 2 hours into 5 minutes.

Hope you enjoy, and if you have any questions, please let me know in the comments.
