 Elwood removes his hat three times in the film: when going to sleep  in his room, to break the window to get into the Palace Hotel, and  towards the end of the movie when the Bluesmobile falls apart. His  sunglasses are never removed. Jake removes his sunglasses once, when  he is talking to Carrie Fisher (qv), but never removes his hat. In  the DVD and cable versions, Elwood doesnt wear sunglasses when he  quits his job.
