Linda Ronstadt apparently isn’t bothered by having her encore drowned out by shouting and booing audience members. A week after being booted out of a Las Vegas casino hotel for the awful crime of dedicating her last song of the evening to controversial filmmaker Michael Moore, Ronstadt is continuing to reference Moore as “a great American patriot” at the end of her performances, causing walkouts, a mix of boos and cheers, and the occasional cry of “Traitor!” wherever she goes.
