The China single, which has become a Tori Amos rarity, contains 4 tracks: 1) China (album version), 2) Sugar, 3) Flying Dutchman, and 4) Humpty Dumpty. Tracks 3 and 4 I have found on plenty of other CDs in my collection, but track 2, the studio version of Sugar, is rather rare. I own a 4 CD set of Tori B-Sides called "Secret Garden", and the version of Sugar that is in this collection is the live version found on the Hey Jupiter single (which is easily available). The studio version is beautiful - a mysterious introduction, great interplay at the end between Tori and the synthesizer, a good beat (low key compared to the live version on To Venus and Back), and an interesting "first" version to compare with how much she changed it as the years progressed. If you are just starting your collection, or even if you are pretty far along, and you do not have this item, then you are really missing something important.
