Thanks for this thread and all these new and old things to listen to! I love covers, so it's hard to choose one. I've always been very partial to Shawn Colvin's version of Steve Earle. Also, while it's hard to best Neil Young, this cut by Jill Sobule and John Doe from the Cinnamon Girl benefit album is pretty awesome. (And a fun coincidence that @frazuli2 just posted another version right before me!)
