In addition to founding channel 3 and serving as the station's original general manager, Howard Fry was best known by children in the Texoma region for his daily program "Uncle Howdy's House Party", which originated on KFDX radio and launched a television broadcast that aired concurrently with the radio program. In 1955, Wichitex sold KFDX radio in order to concentrate on the television portion of the business. Among the personalities who worked at KFDX-TV during the station's early years was Don Alexander—lead singer of rock-and-roll group Alexander and the Greats, and composer of the 1964 hit single "Hot Dang Mustang," which topped songs from such musicians as Elvis Presley, The Kinks, Frank Sinatra and The Rolling Stones to peak at #6 on the Billboard Top 100—who came to the television station in 1964. For several years until he transitioned away from program hosting duties in 1966, Alexander served as host of "Stage Coach Three", a weekday afternoon children's program featuring a mix of cartoon shorts and educational features; as the character of "Pinto Bean", a marshal who appeared alongside his horse sidekick Swayback, he also donned cowboy garb to host afternoon western and horror movies. After filing live reports on the Watts riots, which began as he was starting a planned trip to visit his mother in Los Angeles in August 1965, Alexander was promoted to main news anchor and occasionally headed KFDX's news department as its news director from 1966 until he departed from the station in 1980.
