At one point, Costello went out into the crowd with a wireless mic and we lost site of him but were still impressed. I've seen a few artists go out into the crowd, most memorably Lenny Kravitz, and I always think it's a cool move. Well, cooler than Kravitz going into the crowd (did I mention he wasn't wearing a shirt?) was when Costello showed up in the balcony. He sang his way up a flight of stairs in the Taft Theater and walked all over the place. I was maybe six feet away from the man!
