It's easy to understand why the Van Halen brothers thought they could easily replace Sammy Hagar after he left the band in 1995. The Red Rocker himself was a replacement for David Lee Roth, and the band proved all the skeptics wrong when they sold millions of records with Hagar at the helm. They weren't so lucky with Cherone. The band's 1998 album, III, was a relative stiff, and the tour didn't do the sort of business the band was used to seeing. (Eddie's growing drinking problem didn't help matters, either.) Cherone was a powerful singer and he poured his heart into the shows, but the fans just weren't willing to accept him. Hagar came back in 2004, and then Roth returned three years later.
