The Moanin performance from the final scene is not on the OST, but the Bunkasai medley is, so I'll just use that. You can find it in the OST which you can download from JPS. Title is 'Kaoru & Sentaro Duo in BUNKASA', and it's the 23rd track. If you don't want to download the entire OST I'll upload the single song to mediafire and PM you a link.
Stupid Panda, it's Moanin'. Without the 'g'.
Art Blakey would turn in his grave.
Now listen to the original and be amazed like I was.
Don't waste your breath, son. The Panda has his ways, and they can not be changed.
