Sing is a forgotten classic movie from 1989, starring Lorraine Bracco, Peter Dobson & Jessica Steen.
Supporting cast includes Louise Lasser, George DiCenzo, Patti LaBelle, Yank Azman, Ingrid Veninger and Cuba Gooding, Jr.
A woman returns to her high school as a teacher and convinces the school punk to become involved in the schools annual production "sing".
When the board of education decides to close the school and refuses to allow the annual event to be held, the neighborhood and students come together to put the event on one last time. A cross between "Fame" and "Footloose".
The film was written by Dean Pitchford (who also co-wrote the songs) and produced by Craig Zadan; both previously collaborated on Footloose.
