Danish Orchestra playing theme from The Good, The Bad, and the Ugly.
 

I found their ability to pull this off fascinating. This orchestra seems to have other videos of other westerns as well.

Note the trumpets (my particular instrument). I had thought they they were clumsily arranged in this, BUT when I resaw the movie a couple days ago, I discovered that they had nailed the original sound perfectly.
