18. Van Halen Hire Gary Cherone
Sammy Hagar left Van Halen in 1996, and fans around the world prayed that meant that original singer David Lee Roth was going to return. They appeared with Roth at that year's MTV Video Music Awards, but after a backstage fight they called off the reunion and cut an album with Extreme frontman Gary Cherone. It was a commercial disaster, but the Van Halen brothers would have rather failed on their terms than succeeded with a singer they couldn't stand at that point. In 2004 they toured with Hagar, and in 2007 they folded and did a tour with David Lee Roth. They reportedly kept their distance from each other backstage.
