Fumie Kumatani, Jun Senoue, and Kenichi Tokoi on Sonic Adventure Original Sound Track:

Letz Get This Party Started …for Chao Race Entrance

Kumatani: I edited and used it in the game, but the original version is this kind of feeling. Don’t you think it matches the surreal gameplay and that flashy electronic signage in the scene of Chao Race Entrance?

Senoue: OK~!! OK~!! Here’s a secret of this music that I know. There is a CD with the same title as this music on Kumatani’s desk~!! By the way, the image when I listened to this music for the first time was the feeling of the marching toy wood dolls.

Tokoi: Yes, yes, it used to be called Electric Parade while at work, right?
