It doesn't matter to Linda Ronstadt that some of her fans are angry with her. She says she'll continue to praise director Michael Moore and his film "Fahrenheit 9/11" on stage. In Las Vegas Saturday some audience members, furious with her tribute to Moore, stormed out of her show and tore down concert posters. Ronstadt had to be escorted off the property. Ronstadt told the Los Angeles Times that she's promoting the move because, "this is an election year" and she wants people to "get their head up our of their mash potatoes and learn something about the issues and go vote."
