Is there really any more to add about Van Halen’s long-awaited reunion and subsequent tour with David Lee Roth?

Most fans have followed the decades-long sex, drugs and rock and roll show as carefully as fans of the recently canceled soap opera “All My Children” watched the twists and turns in that story line. And remember how somewhat disappointing it was when the long-awaited event — whether it was a wedding, birth, reunion, or whatever — happened? In a way, Van Halen’s latest concert tour is mirroring that letdown too.
