An insider says, "It was the big what-if of the tour - whether Eddie could stay sober. Wolf hates it when his dad drinks. He knew Eddie was drunk onstage that night, and was acting cold to him, which set Eddie off. Eddie went beserk and started yanking guitar cables from the pedal boards and throwing cigarettes around onstage.

"At the end of the concert, Eddie was so mad at Wolf, he punched the amp speaker, knocking it over." Van Halen enjoyed a stint in rehab last year (2007), which delayed plans for the comeback tour. - more on this story
