Rick Springfield’s version is very well polished since it is a studio version. I admire him for his acting as well as the musical talent. However, Hagar is not only the creator of the song but his emotional delivery can not be matched. The intensity of his body movement and facial expressions make this song an extension of what he feels. You can see the other band members smile at him when he really gets going. I feel he has been through what he is singing about.But then, Hagar worked for Van Halen. They were always intense.
