I am searching a pop music video from 80's/90's. The clue is one man in suit (a vocalist) and a lot of women with guitars (actually, I don't remember guitar sound in the music). These girls were synchronically moving to the rhythm.

It's got to be Robert Palmer's Addicted To Love (http://www.youtube.com/watch?v=F0U5JfGYx4c).
He also did the same thing in Simply Irresistible (http://www.youtube.com/watch?v=XQ-eisHzA84).

Sounds like Robert Palmer... Addicted to Love
