I am always baffled when people expect a jukebox from artists of this caliber. When I go to see an artist I want a unique experience. Dylan is known to rework his songs on the fly live and you never know what you're going to get. He's got one of the best backing bands on earth who can go wherever he wants too. Sometimes it works sometimes it doesn't. Sounds like you might have caught the former which sucks but it's the nature the way he approaches live music. It's anything but safe and doesn't always work. That takes serious guts IMO and it's much more exciting that seeing some geriatric geezer punching out his hits and "collecting his fee".
