I Sing The Body Electric - The Cast of "Fame" (1980)
If you're going to make a movie about a performing arts high school, you gotta have a kick ass finale to end the film and demonstrate the journey the kids have made. Such a song was written by Michael Gore and Dean Pritchard for this 1980 classic that has spawned tv shows, musicals and a remake. This song, and the film it came from, are better than all of these spin-offs combined, and should be watched immediately, especially if the bad taste from the 2009 version is still in your mouth!
Punk rock, you never grow up, do ya? Ya gotta love this!
