Grammy-nominated actor, Huffington Post blogger, and the voice behind many of The Simpsons characters, Harry Shearer performs tonight with his band the High Volume Detainees. Beyond his involvement with Spinal Tap, Shearer has been consistently political: the tunes off his album Songs of the Bushmen focus on President Bush's Oedipal complex and other infamous imperfections, while members of his administration are also taken to task. In celebration of the end of Bush's term, Shearer unloads his impressions of Palin and praise for Obama. Whoever you're rooting for in the fast approaching election, Shearer helps you bid the old guard goodbye.
