This PSA advertisement aired a lot back through out the seventies. I didn't know what VD was when I was thirteen but the song was kind of catchy. I remember the entire family sitting around the dining room table after church. I was waiting for dad's prayer - waiting to eat and for some reason decided to entertain myself with a song. Yes, I knew that it wasn't polite to sing at the table - especially when it's a song about VD.
