CNN ENTERTAINMENT EXTRA: Rock band Van Halen has reportedly fired now former singer Sammy Roy Hagar, in a feud backstage at a recent concert. Reports say that the feud stemmed from brothers Eddie and Alex Van Halen, when they wanted Hagar to stop 'ruining' older songs written by original singer David Lee Roth by continuing to sing them at their concerts. Van Halen has since reunited with Roth for a Summer/Fall tour, and have even re-recorded their new song 'Up For Breakfast', complete with brand new lyrics written by Roth. Mr. Hagar was unavailable for comment.
