I am not sure what the title of this movie is. It is about five guys that are in a psychiatric ward and one of the workers there takes them on a ride into the city. One scene in the movie has all of them singing to the song Hit the road jack. I really need to know the title of the movie. I am not sure who the actors are that are in this movie.

Sounds like you are talking about the movie,"Dream Team" with Michael Keaton as the lead.

P.S. I found this summary on the web.

Plot summary for The Dream Team (http://www.imdb.com/title/tt0097235/)

Dr. Weitzman works with patients in a sanitarium. Convinced that all that his "group" needs is a some fresh air and some time away from the sanitarium, he persuades the administration to allow him to take them to a ballgame. Unfortunately, he accidentally stumbles across a crime in progress and ends up in hospital. The group are stranded in New York City, forced to cope with a place which is often more bizarre than their sanitarium.

Mike is a tad delusional. Harry believes he's a doctor. Jack is an ad executive who believes Jesus is speaking to him. Albert is an adult who occasionally wets himself. When they are taken to a ball game by Dr. Weitzman they witness a murder and Weitzman is attacked and hospitalized. The four crazies find that Weitzman will be murdered as a witness and no one believes four mental patients. They have to both use and overcome their delusions in order to save the only decent doctor who is treating them, with both the police and the killers looking for them.
