I actually remember the case of Clayton Moore from TV news pieces when I was a kid. He was making appearances for two decades without any expressed permission to do so. So did Jay Silverheels as Tonto. Wasn't there an appearance on the Tonight Show?
Wrather only sprung it when he thought he was going to make a Lone Ranger movie. Also, didn't he lose in court? It was also rather embarrassing to Wrather in that Moore was going around wearing sunglasses instead of the mask, until he won his case. His handling g of that case turned out to be a public relations fiasco, and the movie lost money.
All I'll say is that I think he had an interesting place in Disneyland history, and it certainly wasn't all positive.
