I love it.
Why? Well, aside from the hair (because it is fantastic)... and the androgyny (I had a perm in the late 80s-early 90s that made me look a lot like the lead singer)... I simply adore the pure energy in every song! Watch him, he doesn't just sing - he bends, he twists, he lifts the microphone stand, he plays air guitar, he moves around. Now, there are bands that have more energy (Whitesnake)... but, really... how can you watch this and not love it?
