  So exciting - two favorite bands united.  Thanks for this news, kc. 
 Hope there's a video, I can't even imagine what Grace did with it.  I've been watching Wilco  DVDs and have MOB performed at Austin City Limits in 2004.  Another song from that concert that I can see GPN doing is "I'm A  Wheel." It's a total rocker with vocals by the whole band and Jeff does a Grace-like scream at the end.
