For me back in the 80's the song "Automatic"
My jaw hit the floor when i realized that the singer in the song WAS A WOMAN!!! Yep, Ruth Pointer (The Pointer Sisters). For all of you youngins on here, you need to download the song just for the trip. Me and my buddies were watching Night Traxx (man i'm old), and saw the video and our jaws were dropping. Strolling down memory lane folks in my old age. What was the most shocking musical moment that you have experienced ?
