Well if he was expecting Zep then he would be disappointed. The only bit that has any Zep is during Satan your kingdom must come down where Robert adds parts of In my time of dying.
I know its not going to be a Zeppelin night, its folk and americana but I like to see him on stage, enjoying what he's doing having fun and just being up there singing that's something I am happy with.
I know there are plenty of folk who only want him in Zep and hate anything else he does as with AK BOJ and now SG, there are those who didn't like Strange Sensation and SSS especially him doing Zeppelin numbers when refusing to reunite and calling him a hypocrite etc but hey that's down to them. Zep is not going to happen and I would be at the front of the queue if they had ever or ever did in the future.
As I said I'm happy to see the guy doing what he enjoys and is good at cos one day he wont be.
