I'm a massive Dylan fan, good to hear that most people enjoyed the gig-unfortunately I can't make any of the shows on this tour but I think Bob & Mark is a great combination. I'll never understand why some Bob fans dislike Mark, he's a wonderful guitarist and a brilliant songwriter. I wouldn't pay much attention to some of the sarcastic/rude posts on the ER forum, it's pretty obvious that Dylan & Knopfler have a lot of respect for each other and that's all that matters.
For the people who are seeing Dylan live for the first time I'd say don't be concerned by Bob not talking to the audience, he has hardly ever done that but it doesn't mean that he's bored and just going through the motions, it's just the way he is!
