In College, during the 1970s, we used to play "Name That Tune" while listening to one of the Beautiful Music outlets in town. Most of the time, they were playing instrumentals, and lots of the instrumentals were versions of recent and older Pop hits. If we couldn't name the tune, we chocked it up to it being some theater music, although it might have just been some way-older song. I distinctly recall, a number of times, that if the original hit was an upbeat song, the Beautiful Music version might be slower paced. The Debby Boone hit, "You Light Up My Life" was an example, an all orchestrated instrumental, and more upbeat. When the original hit was slow paced, the Beautiful Music version aired might be midtempo or upbeat. Might this have been a way for them to hide the fact that they were playing songs right off of the Billboard "Hot 100" Top 40?
