I understand your comment about his politics. This time he was a little less so. Very surprising and upsetting is he talked about his 3 year old boy John Henry (mother is Allison Moorer)-this boy has autism. Stopped talking at 2 years. Quite sad.
Wow that is truly sad man and kind of out of place for a concert. But I guess he is just that kind of guy everything in his life and on his mind is right out there. That is why I prefer my musicians to if possible never speak i.e. The Grateful Dead for the most part.
He put it in the context of being as old as he is, if he is fortunate he will see this boy through high school, then played a song he wrote for the young one, Remember Me, the last track on the latest recording.
