Thanks, Keith, for bringing this topic back. I'm surprised I hadn't commented on it before.
As others have mentioned, the score to The Sons of Katie Elder is one of my favorites. To quote Hondo Duke Lane, This music touches me in ways that I can't explain. It is what I would describe as a rousing score.
After reading the comments about the score in To Kill a Mockingbird, and also Gorch's reference to Big Jake, I will be watching those films with 'new ears' in the future.
