Yatta!
What a heck? Yatta! Yatta!
So I did a little research. This is a song by group called Happa-Tai, which means “Groups of Leaves”. That’s why the beginning of the song they say “G-R-EE-N-LEAVES!” (not G-i-ee-f-lives! as in the flash, though very funny.) It is actually very positive song. Here is the lyrics (Japanese) and dance to go with it.
