Yeah! Bring him in for That's What The Water Made Me, and then boot him off the stage. Sure he might occasionally do something cool (I haven't even heard this yet so I can't say if I like it... mostly because I just don't care) but the things that he does that are useful far outweighs the negative.

Someone mentioned him playing the lead acoustic on Whole Lot Of Leavin' as something useful that he does.. If he wasn't there, that awful song wouldn't be played anymore. huzzah.
