This just in from The Rev. Beth Maynard, expert on U2 and Theology, an author of the Get Up Off Your Knees sermon collection on U2:
[I want to] make sure you've heard about the first ever-academic conference on U2, being held in May 2009 in NYC. I'm on the planning committee and hope we'll get lots of interesting presentations; the various plenary speakers are promising.
Go here for initial info (more coming in the fall): http://www.u2conference.com/index.php
The call for papers deadline is Nov. 1.
