Doesn't surprise me that Dogs is most difficult... I mean I may be wrong, but isn't Joe basically playing the equivalent of two guitar parts? And just watching him crank it out, you can tell it's challenging... he really puts his all into it, and I swear it looks like he has a ball doing it! One of my favorites, for sure.
And I really hope we'll still get treated to Obscured By Clouds every once in a while... I love the treatment they give it, and I can't get that anywhere else!
