Follow up to my previous post — I finally found the song I was looking for!
I had to repeatedly search for a few words of lyrics, and then “just eyeball” song results until I found fragments that I recognized, which then led me to the final result :-)
It was “The Logical Song” by Supertramp.
Also, though this video is deleted from their Youtube channel, it’s preserved somewhere in DailyMotion :-)

P.S. Sadly, Bard and ChatGPT were’t able to help me with this, though they did suggest a few other ones, which suggests they could be generally useful later.
