Dave was great in Van Halen. No question about it. He was one of the best at being Mr. Rock Star. But it's sickening to see a guy still trying to be that with a wig on 20 years later.
When you are in a band for a number of years you loose your identity in a way. You become a part of that band and then all of a sudden you are not part of that band. You are still the band without the other two members.
