One of the several variations of the "Who am I?" theme song. This one is performed by Jackie Chan - yes, he can sing, and he has quite a good voice! He sings many theme songs for his films too, but the European and American releases have English versions instead, which is a pity, for Jackie's singing is awesomeness!
Enjoy!
