Doing so much work on the tour right now. Desk is covered with all the prep. It's coming together nicely though! Some answers to your questions...
How do we submit questions for the Q+A and/or request a song? Shortly a new site will launch at StevenCurtisChapman.com, and shortly after that, each city will have a place to request the songs played that night. How gutsy and cool of Steven I think. :-)
West Coast and other cities? Currently, only 11/19 and possibly 11/20 are the dates remaining to be filled. I'm sorry to say the Austin, TX date wound up not working out due to touring calendar conflicts in the area. Regarding a west coast, Texas, Tulsa, St Louis, other cities run... there is discussion of a 2011 run by Steven, but no confirmation and it likely would not be with Mary Beth or Caleb. But no definitive word here. And yes, the world is unfair and cruel west of the Mississippi River people, I'm sorry. :-)
The No Q&A cities currently are... Sep 11, Oct 2, Oct 16, Oct 23, Nov 20. This is due to the routing of the tour with Women of Faith dates and what is physically possible. These dates are subject to adjust. No Q&A is subject to the promoter in each city's discretion.
