It was Bradbury who dubbed 约翰·韦恩's singing voice for his "Singing Sandy" Saunders character in Riders of Destiny (1933).
Used his acting money (and singing money, since he dubbed for 约翰·韦恩 as "Singing Sandy" in those cheap Mascot/Lone Star westerns) to pay for medical school. He ultimately became a physician.
