Oh man, I distinctly remember being in grade school in the early 90's and fellow students trying to convince me that "We Will Rock You" was a New Kids on the Block original. Me and my dad's vinyl collection knew better, but no one really believed me.
Like when artists cover a song and younger folks don't realize it wasn't the original.
I'll make a mental note to keep in mind I'm old now so as not to become the old man on the porch screaming at kids.
