Having seen both the original Van Halen and Van Haggar, I can say that the original VH was a far better show, however, the song writing for the Van Haggar songs is far superior. Having said that, the best show I ever saw with them was the 15th Anniversary show at the Whiskey and that was Van Haggar (probably better becuase of the venue, but whatever). I'm forgetting that Gary Charone was ever in VH.
But that was in the 80's and early 90's. Having seen DLR as he's getting older, I would much rather see Van Haggar these days than watch DLR in tight pants and a bare chest in his fifties.
And yes, you will see me in Vegas for the VH show, hands raised throwing the VH symbol!
