A funny thing happened on John Mellencamp's way to Walter Reed Army Medical Center: He stuck a muzzle on himself. Mellencamp has been a vocal critic of the war in Iraq and the Bush administration. But last night, the outspoken singer checked his politics -- or at least his polemic -- at Walter Reed's guarded front gate. During a superlative hour-long concert on the beleaguered military hospital campus, Mellencamp avoided turning the stage into a soapbox, opting instead to simply entertain a group of soldiers wounded fighting a war that the rock star doesn't support.
