According to Ray Waddell of Billboard.com, sources say a Hollywood press conference in one week will announce a 50-date American arena tour by VAN HALEN to begin in early October. The tour will feature founding VAN HALEN members David Lee Roth, Eddie Van Halen and Alex Van Halen, with Eddie's son Wolfgang on bass.VAN HALEN last toured in 2004 with vocalist Sammy Hagar, grossing nearly $40 million, according to Billboard Boxscore. Wolfgang Van Halen, the projected replacement for VH bassist Michael Anthony, told People magazine in April 2007 that he wasn't disappointed there wasn’t' going to be a VAN HALEN tour this summer following his father's decision to check himself into rehab. "My dad's taking care of himself," he said. "I also think I'm too young for the experience, because I know there are a lot of bad things out there." Eddie Van Halen issued a statement addressed to fans in early March announcing that he was seeking treatment because "at the moment I do not feel that I can give you my best. "That's why I have decided to enter a rehabilitation facility to work on myself, so that in the future I can deliver the 110 percent that I feel I owe you and want to give you," the statement said. Back in January, Eddie Van Halen told Rolling Stone magazine about Wolfgang, "Wait until you hear this kid play. I pick him up from school every day and we jam. We've got a shredding bass player now that's laying down the law for Alex [Van Halen, drums], so I get to weave in and out." VAN HALEN was inducted into the Rock and Roll Hall of Fame in March.
