Hey hon, this one needs tending: http://www.videosift.com/video/Hannes-Coetzee-Spoon-Slide-Guitar#leavecomment

When I first learned to play this on the guitar, I always had a hard time getting that high note because it was actually above the end of the fretboard on a standard guitar with standard tuning, and I couldn't get the right note because I was kind of flying blind with no visual marker as to where the note was...now I know it's because he was using a steel-slide guitar! I should have known. D'OH!

It's a dupe from way, way back... http://www.videosift.com/video/Hannes-Coetzee-playing-slide-guitar-with-teaspoon--2

Ry Cooder only recorded the slide guitar parts of the movie, while Steve Vai recorded all other guitar tracks and composed the neo-classical guitar track that wins the battle.
