I saw Eddy Arnold at the 1953 Houston Livestock show and Rodeo. All I remember about the Houston Livestock show is how fat and sleek all the cows and bulls looked. I think it was also called the Houston Fatstock show then.

Bob looks like a cowboy singer now. He dresses in suits that look like Hank Williams and Jimmie Rodgers.

And below is a link that gives a history that says it was in fact called The Fatstock Show in the beginning.
