Rare documentary on the music for The Empire Strikes Back

Tracksounds has compiled a great playlist featuring a rare documentary on the music for The Empire Strikes Back.
 
Here’s the Youtube description:
 

This is an ultra rare documentary made during the making of the Empire Strikes Back between 1979-1980. If you consider this the best of the Star Wars films and love the score then this is the holy Grail of documentaries.
