So at the office today, I was having fun asking people the question about the singularity of the Lone Ranger when an agent "of a certain age" politely told me: "Because he was the only survivor of an ambush of Texas Rangers, and he made his mash out of his friend's shirt." I was stunned. I had never heard this.
I have no reason to doubt her, she said she used to listen to the Lone Ranger on the radio before T.V. The program would star when she was visiting her grandparents, and her father would go out, crank the car and "warm up the radio" then honk for her. She would then fly to the car as fast as her legs would carry her, so as not to miss a moment of the drama.
And too, I think I have heard it as "The Lone Ranger and Tonto" or can easily convince myself I have.
