Broadcast television only has one real power - the power of repetition.
Imagine this, for two years, 1968 and 1969, this Camp Fire Girls PSA ran before, and after, every cartoon, all day on Saturday mornings. Try as you might, no one could escape hearing this ad short of turning the TV off completely. Then you could hear it from the neighbor's open window!
But then a strange thing happened - this PSA became an unofficial Saturday morning anthem. After hearing it a few hundred times this soundtrack sort of permeated every weekend. Personally, I could hear it in my head late into the evening. I could hear it as I lay in bed looking up at the night sky.
Never realized how much this song got to me - until the ad was pulled by Campfire USA.
The audio recording is awful, Thomas Edison could've done better with a needle and a wax cylinder. Maybe the bad recording is part of this PSA's charm. After 50 years I can only make out two lines of lyrics. The rest of the music is from an original garage band that I've never known the name of.
