He has been more responsive, which is an incredibly encouraging sign,” publicist Lewis Kay said Sunday.

The wreck took place about 1 a.m. Saturday when the limo van Morgan was in was hit by a tractor-trailer on the New Jersey Turnpike, police said.

The collision killed Morgan’s fellow passenger, comedian James McNair — who performed under the name Jimmy Mack.

The driver of the truck faces criminal charges; Morgan had performed Friday night at Dover Downs Hotel & Casino in Dover, Delaware.
