10. 'Dreams' (1986)
A lot of bands don't survive the departure of a lead singer, especially one as charismatic and famous as David Lee Roth. But Van Halen brought former Montrose frontman Sammy Hagar into the band in 1985 and had a huge hit right away with 5150. "Why Can't This Be Love" was a smash right out of the gate, and they scored again with "Dreams," the follow-up single. They shot two videos for "Dreams." One showed the Blue Angels doing aerial stunts, and the other showed them playing the song live at the Whiskey A Go Go, when they were celebrating the band's 15th anniversary. We included the latter one here. Right around this time, David Lee Roth hired Steve Vai as the guitarist in his newly formed solo band. He started scoring hits of his own, and for a couple years it seemed like both Van Hagar and David Lee Roth would be equally popular, but that was not to be.
