Youve never heard this before Sonic 3 D Boss Fight Music Demo

Never heard demo version of the Boss fight music. There are two versions, one with a minor key intro and one with a major key intro. These demo tracks were recorded by SEGA for my approval before they were used to base Sonic 3D s music on. I m preserving them here. After the fires a few years back and new ones nearby recently, I would hate these demos to be lost forever. Track composed by Jun Senoue
