Linda Ronstadt has been offered a return engagement at Las Vegas' Aladdin Hotel Casino -- from which she was escorted by security guards on July 19. Aladdin president Bill Timmins had her ejected after some casino patrons objected to Ronstadt's onstage praise of filmmaker Michael Moore and his Fahrenheit 9/11. Now, the Aladdin's prospective new ownership says Ronstadt would be welcomed back. A division of Planet Hollywood is pursuing ownership, and a company spokesman said the company had never restricted any artist's right to free speech. Speaking for the new ownership, Robert Earl said, "Upon the assumption of ownership, and with a new management team in place, we would like to offer the use of the Theatre of Performing Arts to Linda Ronstadt for a second concert and further to take Michael Moore up on his offer to join her on stage to introduce her and sing a song." Neither Ronstadt nor Moore has responded to his offer.
