Former Van Halen star Sammy Hagar fears the group's much-hyped reunion tour will fall flat without original bassist MICHAEL ANTHONY. Anthony has been replaced by Eddie Van Halen's teenage son Wolfgang for the upcoming tour, and the band's Why Can't This Be Love singer insists fans won't appreciate the line-up change when shows begin. Hagar tells website KNAC.COM he would have refused to tour without Anthony - if he had been asked to join the reunion lineup. He says, "If Eddie wants to play with his son, fine. I love my son too, but I got him a different job. I just think that it should be Mike. "I just think the fans are gonna walk away with a little bit of a disappointment because Mike's a big part of that band."
