Name That Tune

Name That Tune is by far the oddest game show in American history. It baffles me. I understand the premise easily enough, but what troubles me is that people watched it. The songs they played and then named in two or three notes were usually classical pieces. I don't know anyone who could name classical composers at the level that contestants on the show did. I understand Jeopardy, you can usually guess a few of those in each category, but classical composers? It's not so weird that people can name the songs, but considering the kind of audience most game shows have, who was tuning in and watching it? It seems unlikely that the classical music and game show audiences would overlap enough to make a show like this even mildly popular, but it somehow stayed on the air for years.
