As long as people do it respectfully I don't mind. But making others, especially children, breathe in your smoke is disgusting. I worked at a kids hospital for years, and people, including nurses, would light up right at the entrance, forcing the parents and (sick) children to walk right through their smoke. Disgusting.
The track Ghosteen is in my top 5 Cave songs for sure. Some bizarre opinions in this thread.
The gig at the O2 was great. Absolutely loved the Wild God stuff but I'm a bit miffed that he seems to have settled on what his greatest hits are, and I largely disagree with his choices.
The days of getting slightly unusual songs like Watching Alice or something like that seem to be long gone. As are getting different setlists on different days of a tour.
