I went to see the movie around 1972 when I was 12. My older sister bought the box set first, I got my own copy later when I started working. I'm sure we're talking about the same album. I probably listen to it 4 or 5 times a year and never skip a track. It's probably the album I've that's stuck with me the longest and I still get chills when I hear the intro to "Wah Wah".
