Very nice idea! Yet, Youtube tells me, that "unfortunately, this video is not available in Germany, because it could include music, that the GEMA has not given the necessary music rights". Well, could you post it on Vimeo instead?
I usually play with various children songs, thus, my children have fun, and I have too, while taking care of them and simultaneously taking care for myself ... ahem.
The classic "Usagi to Kame" song is of course my favourite one:
The funny thing about this is, that it is played slower (about 105 beat per minute) than the JKA wants the Dan Grades to be played (keys are noted in 105 beats per minute, while JKA asks for 135...). Well, I think faster is more fun. I also love playing Moshi kame while my wife is playing piano. Well, she hates it ;-). Music is great for training stupid tricks in endless repetitions, anyway.
