Thinking about it, there really is no artistic justification for this tour, is there? I mean, they played five songs together last night, and Mark's playing sounded superb, but Bob was still doing his thing. It didn't feel like a collaboration. I don't know, I could have done without it. To me, it was kind of pointless. Mark should enhance his own songs, and Bob should do his thing. It's just my impression but I had the feeling they don't fit together, on an artistic level.
