I promise I will keep your secret!
When my Dad was bring home all the demo LP's, he kept all of the easy listening for him and my Mom, and gave me all the good stuff, LOL!
The restriction was I had to play them BEFORE he got home in the afternoon!
Wish I still had them all.
I have tons of those "Demonstration only" Lps L0L
That must have been way cool to have an inside connection :)
