The producers go to great pains to ensure that Clayton Moore's face is never shown, shooting from behind, covering it with bandages etc., until the Lone Ranger finally dons his mask.
It seems there has been an error of omission. It's puzzling that a symphony orchestra's music for all the dramas remains uncredited.
The Lone Ranger (1949) premiered on September 15, 1949, exactly one day after Clayton Moore's 35th birthday.
