Myth: The man who wrote Don't Worry, Be Happy killed himself.
Reality: As sensationally ironic as this story would be, the songwriter behind this upbeat Eighties ditty - Bobby McFerrin - is actually alive and well, and still happily making records. On the other hand, the man who wrote First World War hit Pack Up Your Troubles In Your Old Kit Bag And Smile, Smile, Smile, really did end his own life, in the midst of the Second World War.
