It's really interesting that someone would ask this.
I'm a classical percussionist and back in Jr. High School in '72 my orchestra performed the soundtrack from Man Of La Mancha by Francis McBeth.
It was a magnificent score, my part on the Timpani was the BOMB, it would bring you out your seat. However my never experiencing the movie, I didn't know the plot or the characteristics to this great film so I didn't have an appreciation for it from other than a performance level.
Two weeks ago Man Of La Mancha with Peter O' Toole and Sophia Loren came on TV and I finally watched it uninterrupted in its entirety.
I'm a little embarrassed to say that after 37 years, I finally get what this movie was about! Embarrassed because I didn't let the greatness of this movie in, while the opportunity was directly in front of me as a child.
This is one movie that I was damn glad to see at last.
There are other notable soundtracks I've performed "Zorba The Greek", "Exodus", "Doctor Zhivago" and "War & Peace" that I haven't watched yet as well. And they are all now on my "Must Watch" list!
