Van Halen has broken up and reformed so many times over the years—with different lineup combinations—that the group rivals Fleetwood Mac for dysfunction. Brothers Eddie and Alex Van Halen formed the band with lead singer David Lee Roth and bassist Michael Anthony in 1972, and the group enjoyed success throughout the mid-1980s before Roth left in 1985 to start a solo career. Rather than split up, the band replaced Diamond Dave with the already-established singer Sammy Hagar, who helped shape a new era of Van Halen and land three more multi-platinum albums. Roth made an appearance with the group at the 1996 MTV Video Music Awards, but there would be no reunion of the original lineup until a decade later (following a reunion with Hagar). The following year, Van Halen (including Roth and Hagar) was inducted into the Rock and Roll Hall of Fame.
