It's got to be hard to be a band that's trading on your 40-year-old hits, where there's a certain thing that's expected of you. But that's why I admire Bob Dylan's live performances - he's steadfast about mixing up the songs, not just sticking to his greatest hits, and reinterpreting them to the extent that you really can't recognize them until halfway through. It's like, I DARE you to sing along.
