Those photos of Florence, Alabama moved me to post this, a Dylan cover of the Grateful Dead's Alabama Getaway from 1997. I heard Dylan do this great song in New Haven around that time. Same band. He had so much incense or smoke or whatever he uses that you could barely see the band through it. And he did shake hands or slap hands with everybody up front, too. I do remember that he opened with a rousing Crash on the Levee that night, and did an acoustic set too including Girl from the North Country.
My theory is that he always likes to keep his band off balance and challenged. I do not think that they rehearse. Dylan was playing some interesting electric at this time.
