I noticed today that KTXR has gone to "The Great Hits of All Time" when did that happen? It sounds good though.
When I lived in Springfield, back in 1993, KTXR was an easy-listening format. It was practically identical to the format of the radio station I worked at at the Lake of the Ozarks a few years earlier. It was 80 percent instrumental/20 percent vocal. The music was pre-programmed by Bonneville and sent to the station on reel-to-reel (later CD). The format was executed by playing one vocal every 15 minutes (every 10 minutes during the morning drive) and the rest of the hour would be instrumental. The vocals were a combination of light AC & MOR, so it was quite common to hear Frank Sinatra or Peggy Lee and then hear Phil Collins, Whitney Houston, or even the Miami Sound Machine 15 minutes later. About 80 percent of the instrumentals were instrumentalized versions of MOR, pop, & rock songs from the 60's onward that were done in new-age-jazz-style fashion. A great majority of these were arranged and recorded by Bonneville's own studio musicians. The rest were performed by various well-known instrumental guitarists such as Chet Atkins and Earl Klugh. The remaining 20 percent of the instrumental library consisted of instrumentals that were mainstream popular hits (examples: Music Box Dancer by Frank Mills or the Alex F Theme by Harold Faltermeyer). I moved away from Springfield in 1994, so I don't know when KTXR dropped this format, but the "Lake" station I worked at was still carrying this format when it shut down in 2001.
