When I think about wam in music video, my mind comes to Duran Duran's "Girls on film" video.
It appeared in early 80's, when I was a late teen full of hormons, totally unaware about wam and its pleasures. Just saw video another time, and now seems to me showing "just" a brief scene of nonnude pussies on a greasy pole, and a longer scene of girls wrestling in mud but, hey, at that time it appeared to my eyes as most exciting video ever seen.
I remember well that, at mud scene, I thought "mee too !". And when, a tenth of year later, I dicovered wam throught the net, I got into a story involving two girls sliding their pussies on a greasy pole. And my mind istantly came to Girls on film video.
I' m aware that many messier music videos appaeraed later, but, in my mind, that video opened my mind to wam universe.
