London: Rock group Van Halen has cancelled a few comeback performances so that guitarist Eddie Van Halen can go back to rehab to be treated for alcoholism.

The band rescheduled two concerts in Virginia and Georgia raising rumours that the tours have been cancelled indefinitely, contactmusic.com reports. Representatives for the band say the tour is on even though Van Halen "is undergoing a battery of comprehensive medical tests to determine a defined diagnosis and recommended medical procedures".

Sources say Van Halen decided to check into a rehab after he had a major argument with his 17-year-old son Wolfgang backstage.

An insider said: "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 that night, and was acting cold to him, which set Eddie off. Eddie went berserk 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."
