That was a great show, best of the 5 times I have seen them, and I was completely sober so my opinion was not swayed by alcohol. Bob and Nate were pretty drunk but they still performed great and they are pretty funny when they get that drunk. The 2 encores were fantastic. And as Bob commented, they were digging deep in to their catalog. They may not have played as many of the usual standards, but they added some great songs to the setlist for this tour that they have not played in a while. Liar's Tale and Hey Aardvark were particularly good. And the second encore was not on the setlist, they don't always do two encores, so they seemed to be enjoying it.
And his comments on professionalism were not that they could play get back, he was saying, in his normal joking way, that the spotaneity was professional. They had just finished playing Back to the Lake which includes the words "get back" and he said, lets play get back. It was really fantastic, he has a real talent for covering Beatles and Who songs.
It is weird that the 2 times I have seen them at Recher I end up standing next to the only person that gets thrown out. The guy who was next to me for most of the show (no Markie, it was not lefty) was so drunk that his eyes seemed to roll back in his head as he flailed around. When he finally managed to accidentally toss his beer bottle on stage he was booted, to the relief of all around him.
