Guitar Hero 1 (PS2): Original Beta Build/Unused Beta Elements

In 2005, the first Guitar Hero rocked the masses (see what i did there?) with it's innovative guitar controller and gameplay style. Critics gave it overwhelmingly positive scores, and for a point in time it was the best selling PS2 game. (Although eventually that was taken by Grand Theft Auto: San Andreas.) However, the original beta build of Guitar Hero was completely different from the final build. The beta remained in obscurity until a video was posted in 2007 of it.

Interesting differences in the video include: The only evidence for this build existing was the 1 minute and 28 second video showing Spanish Castle Magic with vocals. The beta build has not been resurfaced anywhere, and there is no other screenshots or videos.
 * 1) The colors of the frets are the colors of the rainbow, with the exception of the colors indigo and violet.
 * 2) The song Spanish Castle Magic was going to have vocals, as seen in the video.
 * 3) There are no hammer ons or pull offs.
 * 4) The graphics and animations are different.
 * 5) The score gets built up in sections and then added to the current score, like the game Karaoke Revolution.
 * 6) There is no star power anywhere.
 * 7) The star power bar was a bar that showed how well you were doing during a scoring section.
