I got to know those Rozsa scores in reverse: King of Kings (which I played to death, and went to repeatedly), then Ben-Hur which I caught up with later. I hadn't yet been going to movies by myself before 1961, and my family had never gone to see Ben-Hur in a theater.
Loved those box sets so much, with the hardcover souvenir books. I still have them, but they are not my originals which were trashed. Also have the other two that MGM issued, Brothers Grimm and Mutiny on the Bounty.
