The only movie that ever properly integrated this song...

It was the progenitor of the "Silence of the Lambs". Watch it, it is a great movie.

I don't recall if the film had the entire 17 min song in it, but it has more than that video clip showed.

 

The "anthem" of hippie music...

There is a shorter version too, suitable for radio play...
