One of my favorite songs of the last decade is certainly Wilco's "Jesus Etc". The song is not only beautiful, but really fun to play (thanks Al).
At last weekend's Bridge School festival in California, it was not only played by Wilco but also a fantastic version was performed by Norah Jones. Jeff Tweedy had to be a very proud songwriter that night.
A great quality video is below as well as Wilco playing it from back in August.
