To me, the Sam era represents an inferior version of VH, so there's zero reason for me to ever want to see that lineup again. The Dave era songs are better and Dave is/was a better frontman. Plus, the world doesn't need to see a 70 year old man in capris bullshitting around onstage. I have zero interest in anything this lineup could give, whether it was a tour or studio album.
Dave's 2nd act with VH may be coming to a close, but I sure as fuck don't want to be slathered in Sam era velveeta again, which I would be even if I chose to completely ignore it.
