As a kid I had heard Got my Mind Set on you by George Harrison on the radio once or twice.
A few years later when I was starting to listen to music for myself I heard the Weird Al parody, and wanted to track down the original. I didn't remember any lyrics to the original so the best I could do was accost people with a very poorly sung chorus of "this song is just six words long."
It didn't go well. I didn't find the original until the Internet had caught up enough for me to find it easily.
I had a similar arc with Downtown by Petula Clark. Thankfully without me trying to sing a parody chorus at anyone.
