Car Wash is notable not only for it s cast (including Richard Pryor and George Carlin) but also because the soundtrack (written by Motown producer Norman Whitfield and performed by the newly-formed Rose Royce) was released in advance of the movie with the first single (title song) reaching #1 on the Billboard charts the same week that the film was released; the 2nd single I Want to Get Next to You made it to Billboard s Top 10 National Pop Singles chart. Reissue features digital remastering and dialogue from the film.
