The slide playing on Donegan's Gone itself is terrible. And I also think that the Dark Was the Night intro doesn't match. It would fit much better to a more bluesy song, Marbletown for instance.
Here's a thing with Mark though - for me he is a MASTER of tasteful lines. And the tone, oh, man ... But sometimes he just surprises me with some really corny choices of notes. I don't have any examples off of my head, but it's usually during a longer solo phrase where he sounds like he doesn't quite know where to go, and he chooses the easiest way out. And sometimes he just gets himself into a big mess haha As was particularly evident on Sultans during the Crimson tour.
