Yes, I had that 45 in 72. When I was in college much later, the multi record LP said that the professor required us to buy had that song on it. When I told him I had that in my record collection as a kid he asked me what was on the other side of the 45? I told him I didn’t know I never flipped it over. I have it to this day on my iPhone.
Not sure if this was based off a classical composition like "Joy" was or an original composition by Apollo 100, but thanks to YouTube, which has pretty much every piece of music ever recorded, you can hear it at the link below and despite the title, it does not feature Richard Simmons in leg warmers, I promise.
I don’t if I ever listened to the flip side either. I just listened to it on YouTube and it was not even vaguely familiar.
