Ralph David Foster was an American broadcasting executive and philanthropist who created the framework for Springfield, Missouri, to challenge Nashville, Tennessee, as the nation's country music capital during the 1950s. His KWTO was a stepping-stone for many top country artists; and with his music businesses, led to creation of Ozark Jubilee, the first U.S. network television program to feature country's top stars.

Clyde Carol Wilson, better known as Slim Wilson, was an American singer, songwriter, bandleader, and radio and TV personality who was a cornerstone of country music in the Ozarks for more than 50 years beginning in the 1930s; both in his own right, and as a member of The Goodwill Family and The Tall Timber Trio. Wilson was a mainstay of ABC-TV’s Ozark Jubilee; and hosted ABC's Talent Varieties in 1955 and his own local television show in Springfield, Missouri, from 1964 to 1975.
