20 years after Sammy Hagar replaced David Lee Roth in Van Halen, it occurs to me that I like the Hagar-era songs better. Why? I'm not sure exactly. I have a theory, though.
When I was single and hanging with other singles, we'd be in a large gathering at someone's house, and there's always that one person who came in and announced him/herself with a shout. Something like "Who's ready to party?" or maybe just a simple "Woohoo!" People who do that have always been a turnoff to me.
Now that I think about it, Dave was more like that guy. Always having to draw attention to himself, reminding people how fun it is to have him around. But the songs of the Hagar era were more about the song than the guy singing them. They didn't scream out "see how cool I am!?!" They were just good songs.
