(AP Photo/Seth Wenig, File)LOS ANGELES – You can get anything you want at Alice's Restaurant. But it appears we've seen Arlo Guthrie tell us that in person for the last time. In lengthy posts on his Facebook page and website, the 73-year-old folksinger announced Friday he is retiring from performance immediately. He's canceled numerous shows he had planned around the country for the next year and said he won't be booking any more. Guthrie, who frequently declined to play “Alice's Restaurant Massacree” for audiences over the years, had planned to perform it at next year's shows.
