Van Halen with DLR - concerts to be better than old ones?

If you’ve ever watched video of VH in the old days, you immediately notice that DLR couldn’t be bothered to actually sing all of the lead vocal. Was he consistently drunk (US Festival?), or is he just an artistic jerk? I get frustrated with him, and it’s not my music he’s screwing around with.

Is there any reason to believe that he’s not going to do the same thing on this current tour? If he does, I could see Eddie firing him again, for effectively the third time.
