Mbo,Van is like Bob in that they both have over 35 years of material to draw from. I'd have no problem if the show was 50% the new album and the rest was a mix of just some of the songs that you already knew and loved, keeping in mind that for either of these artists to do every song that you'd like to hear them perform in one evening would be impossible.
When people asked me what I disliked about the show my response was 'Name a Van song that you like' No matter what song they named my reply was the same, "He didn't do it" or "He left the stage and his daughter did it"
I had seen Willie Nelson a few weeks prior to the Van show. Willie does a great job of performing new material while also trying to play every song that you've come to love. My take was that Willie performs for his fans, Van does it for his ego, pretty much saying F you, I'll do what I want.
