Can anyone help me find an old Miku song?

I don't think it was ever hugely popular, but I loved it and I lost it when I lost my old YouTube account.

It uses Miku append Strong, and it's her singing a traditional Japanese summer bonfire festival song. It's not a modern pop song, it's just her voice and a few traditional instruments. The video was a still of her in a summer yukata.

It was one of the first songs that really did sliding pitches and tones really well.

I can't find it because the text was all in Japanese.

All I remember is this cute pitch whete she goes "A chu chu, iki demoooOOOOooouuu"
