McSpadden was involved in rodeos throughout North America as a broadcaster, including the National Finals Rodeo in Las Vegas, Nevada, the Calgary Stampede, and the Canadian Finals Rodeo. In 1974, he hired a then unknown Reba McEntire to sing the National Anthem at the National Rodeo Finals. He was quoted by the Tulsa World as observing "an amazing correlation" between politics and the rodeo profession, "in that there's bull in each profession." He is also known, especially through the rodeo community, for his authorship of "A Cowboy's Prayer."
