David Lee Roth and Eddie Van Halen

Band: Van Halen

It was all smiles when Van Halen reunited last year, but once upon a time, even in the midst of their hard rocking, stadium shaking glory, lead singer David Lee Roth and guitarist Eddie Van Halen were bickering. Apparently this led to Eddie asking Gene Simmons of Kiss if he could join his band in 1982. Eddie kicked Dave out of Van Halen in 1985, right at the exact same moment Dave quit (if you ask him).
