Kendall-Shredded Ralston (now Wheat Chex) sponsored Tom Mix, which starred Curley Bradley. The tune was Round-Up Time in Texas, or When the Bloom is on the Sage, whichever.

Sgt. Prestons's theme was the Donna Deanna Overture by Resnichek (sp.?)

Did any one mention "Cheyenne, Cheyenne, where will you be camping tonight?"
Lonely man, Cheyenne with your heart so free and light.
And when you settle down, where will it be? Cheyenne"?
