Riddle: A poor man was sitting at a bar. A rich man walked and sat down. He gave the bartender a 50. The poor man said," I know every song ever created." The rich man laughed and said," If you can sing a song with my daughter's name, Sarah Beckenham Hart in it, I will give you all of my money. The poor man went home rich and the rich man went home poor. What song did the poor man sing?
