DETROIT (AP) - Musician Sheryl Crow is scheduled to perform at the black-tie charity preview for the North American International Auto Show in Detroit. Friday night's performance comes a day before the show opens to the public. A ribbon-cutting for the charity preview takes place earlier Friday. The performance is set for the new Cobo Atrium, after the show floor closes. Tickets for the charity preview were $350 each. Since 1976, organizers say the charity preview has raised more than $91 million for a number of southeastern Michigan children's charities. The auto show runs through Jan. 26.
