Lyrics for Films

I was asked a few months ago to write a creepy little poem that children would sing like a nursery rhyme for a horror film. I wrote 3 different renditions for the writer. I believe they put that project on hold though because I have not heard a thing about it since. Yesterday I received a DVD of a documentary that the creator of wants me to watch to see what lyrics it would inspire. So I will watch it with paper and pen nearby. I know the subject matter is difficult and I hope to do it justice.
