When you see RJD sing, that is what you hear. But not the music. The music is from the studio album. Watch Blackmore's hands. They don't match what you hear, and what you hear is the studio version. He always improvised this solo live. Seems as though they recorded a performance and had to import the studio trax due to a problem but kept the vox. Amazing thing is the tempo. It synchs perfect and this is way before live click trax. Rip, Cozy!
