I'm glad I chose this movie. I knew I would like it, because I loved the soul music of the 60's and 70's. Not just the music and singing, but the choreography and the flashy, polyester suits that was so popular with groups. 
The film tells the story of two back-up singers from a popular R&B trio in the 1970s. When their lead singer went solo, and became extremely successful, the same wasn't true for Louis Hinds (Jackson) and Floyd Henderson (Mac). They go their separate ways, and lose contact until 20 years later when they are notified of the passing of their former successful partner. 
Louis and Floyd have interpersonal issues and really can't stand each other, but one has a need to pay his respects and the other has a desire to cash in. The embark on a road trip from Los Angeles to New York.
The movie is very funny, and has several messages. The obscene language is a bit over the top, but then again it's two hard core, aging has-beens dealing with their own issues and each other.
They are asked to come together again in a tribute memorial celebration at the Apollo Theatre in New York.there were only five people in the theatre, and we all laughed out loud often! It was especially touching with a sense of nostalgia generated by the movie's postscript affectionately acknowledging the passing of both Bernie Mac and Isaac Hayes.
I give this movie four gramophones out of five.
