Celine Dion's show-stopping performance at the 2003 auto show Charity Preview may be the last of its kind. Taking into account post-event dealer input, the show's organizers are working to make sure the cars remain the stars at Detroit's biggest social event, according to a report in the Detroit Free Press.

Entertainers like Dion "are good for interest in the event, but raise concerns about the comfort and safety of our guests," said Chuck

Fortinberry, 2004 North American International Auto show senior cochairman, the Free Press reported.

Dion's three-song set on the Chrysler stand at the 2003 Charity Preview drew huge crowds and overshadowed the rest of the evening; some showgoers missed the relaxed air of prior years.

"Having an entertainer of Celine Dion's level creates problems for comfort," Fortinberry said. The Detroit Auto Dealers Association (DADA), which sponsors both the auto show and the charity event, has asked automakers not to schedule potentially disruptive A-tier entertainment acts without its agreement, he said, the Free Press reported.

Some automakers may want to bring high-profile

entertainers to the 2004 Charity Preview, said auto show cochairman Bill Cook, who declined to name them, according to the Free Press.

A Chrysler spokesman was unaware of the dealers' position and had no immediate response. "General Motors is in full support of how the dealers feel," GM spokeswoman Susan Reyes said, according to the Free Press.
