The melody was written by the company that made the demo for me. I am not familiar with the song you had mentioned, but do recall a Tom Jones song called "Delilah". But I fear that now that there are so many lawsuits brewing, soon people might be afraid to create anything. I just heard of another potential one on the radio just yesterday. It seems that in recent years there has been a dramatic increase in suits related to copyrights and trademarks though.
