We have lived in Las Vegas for 21 years. In the early 1990's when we first learned that Van Halen was taking aboard Sammy Hagar, frankly we were relieved. After Sammy came aboard with VH, we attended two concerts of theirs in Las Vegas. Once at The Mandalay Bay Event Center and one at Thomas Mack. Although we enjoyed these shows, we had seen 2 VH concerts previously with David Lee Roth. After attending our first VH concert with Sammy at the helm, it was clear that the change was the best thing to happen to Van halen.
