Rock supergroup Van Halen's postponed summer (07) reunion tour is back on, according to U.S. reports. The 40-date trek, featuring Van Halen brothers Alex and Eddie, Eddie's teenage son Wolfgang and frontman David Lee Roth, was derailed when guitarist Eddie checked into rehab for alcohol-related issues earlier this year (07). Reports suggest the tour may be resurrected as an autumn (07) arena run. Several dates are in place, according to Billboard.com, but they're yet to be confirmed. The delay has given bass player Wolfgang the chance to hone his skills for the tour after admitting he was relieved the summer tour was called off. In an interview back in April (07), the young rocker said, "I think I'm too young for the experience, because I know there are a lot of bad things out there."
