I completely get this and fair do's to all who share this view.
For me, quite simply it's Genesis - yes, different from before but it's them and I want to be there. I just don't think that when I am it'll be 5 months from now.
Ultimately, as I always said, this is what matters. We all love the band I'm sure but I'm equally sure, we love them in very different ways and they mean different things to us. I'm not immune to nostalgia, recreating a moment, when possible, has its charm and why not wallow in that a little? I just can't see them like that and i prefer to accept the fact that the moment is gone but again, I'm extremely happy they decided to do it, for them mainly and then for those who want to enjoy them.
