This song (Tomorrow Belongs to Me) has always inspired mixed emotions as far as I am concerned.

I have linked to this version rather than the movie clip because this video is a little more thought provoking.

I happen to think it is a truly great song, but in the movie it acquires horrendous overtones .

I know it isn't a folksong and that it was written for the musical, but it does have the timeless quality that all great songs have, whether "folk" or not.
