Randy Rhoads private lesson with Peter Margolis , who tried diligently to get a film made but unfortunately The Osbournes had other plans like ruining it and not licensing the music.  

You can hear Randy play an early version of Steal Away the Night.  He also rips players who are more interested in their equipment and sound, versus playing music.

Peter ended up putting out the best biography ever written about a musician with Andrew Klein and @Goodwriter  , Randy Rhoads coffee table book.
