I think Chris is very talented and I have been reading alot of stories on the internet that the backlash on him has begun. Such a shame.
I read somewhere that they sold out 1 night at MSG. They had good crowds overall even though some shows were not sold out. But they did sell out a few shows along the way and the seats were smaller venues which is much better for that type of tour, IMO. Besides, what difference does it make anyways? If you are comparing their ticket sales to Zeppelin, you are absolutely right, apples to oranges indeed!
